Combining Scripts/Commands into a single execution

Hi David, I currently have to do a 2 time manual pass to rename my photo files using the methods/scripts and process outlined below. This works well, but I have to do 2 x stage manual process.
Is there a way to combine/structure these commands/scripts that would allow me to do a 1 time fully automated execution/pass?.
Note: The original file name dates and location are known in advance allowing me to construct my CSV file.

Original File Names (out of camera)
-8503919
-8503920
-8503921
-8503922
etc.

Execute the following:

Remove Count 8 Starting at 1
Add ExifTool:Createdate
Remove Count 8 Starting at 1
Add <Inc Nr:001:1>

Prebatch Script
lastDate = "";


Script
name = item.newBasename;
if ((date = name.slice(0,10
)) != lastDate) {
lastDate = date;
incNo = 0;
}
return name + " " + ("00" + ++incNo).slice(-3);


Remove Count 5 Starting at 5

Executing the above results in

2020_11_02_001.NEF
2020_11_02_002.NEF
2020_11_02_003.NEF
2020_11_02_.NEF
2020_11_06_.NEF
2020_11_06_002.NEF
2020_11_06_003.NEF
2021_01_26_001.NEF
2021_01_26_002.NEF
2021_01_26_003.NEF
2021_01_26_005.NEF
2021_02_01_001.NEF
2021_02_01_002.NEF

I then start the batch to update the names in the direcotry and then drag these new files for renaming into the app;

I then Execute the following Script

Pre Batch
replace = {};
csv = "C:\\Users\\John Johnson\\Desktop\\Script Test\\Date Location.csv";
csv = '::\"' +csv + '\"';
j=1;
while (line = app.parseTags('<File Line:' + j + csv + '>')) {
match = line.match(/(.*),(.*)/);
replace[match[1]] = match[2];
j++;
}



I Run the Script using the CSV File below

match = item.name.match(/([^ ]*)(.*)/);
place = replace[match[1]];
if (place) return match[1] + " " + place + match[2];


2020_11_02 Black Bear 001.NEF
2020_11_02 Black Bear 002.NEF
2020_11_02 Black Bear 003.NEF
2020_11_02 Black Bear 004.NEF
2020_11_06 Library Springs 001.NEF
2020_11_06 Library Springs 002.NEF
2020_11_06 Library Springs 003.NEF
2021_01_26 Rolling Meadows 001.NEF
2021_01_26 Rolling Meadows 002.NEF
2021_01_26 Rolling Meadows 003.NEF
2021_01_26 Morton Arboretum 005.NEF
2021_02_01 Morton Arboretum 001.NEF
2021_02_01 Morton Arboretum 002.NEF

CSV File
2020_11_02,Black Bear
2020_11_06,Library Springs
2021_01_26,Rolling Meadows
2021_02_01,Morton Arboretum

This should work...

Pre batch script:

places = {};
incNrs = {};
csv = "C:\\Users\\John Johnson\\Desktop\\Script Test\\Date Location.csv";
csv = '::\"' +csv + '\"';
j=1;
while (line = app.parseTags('<File Line:' + j + csv + '>')) {
match = line.match(/(.*),(.*)/);
places[match[1]] = match[2];
incNrs[match[1]] = 0;
j++;
}

Main script:

date = app.parseTags('<ExifTool:CreateDate>').slice(0,10);
if (place = places[date]) {
return date + ' ' + place + ' ' + ('00' + ++incNrs[date]).slice(-3);
}
