Insert "Location Description based on Date

I have photo shoots on different locations on different dates and would like to use an automated script to insert a location description based on the date of the image taken. The image files have been processed to reflect the date and uniquely indexed based on the date (see below) and I now want to run a script which will insert a given location name based on the specific date of the image. Example as follows:

Current processed file name:
2020_11_02 001.NEF
2020_11_02 002.NEF
2020_11_02 003.NEF
2020_11_06 001.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_26 004.NEF
2021_02_01 001.NEF
2021_02_01 002.NEF

Want to achieve this;
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

Help is much appreciated

If you only have a limited number of date/location pairs then just use the List replace method with one line for each replacement...

Replace (2020_11_02) with \1 Black Bear
(2020_11_06) -> \1 Library Springs
(2021_01_26) -> \1 Rolling Meadows
(2021_02_01) -> \1 Morton Arboretum

Use regular expressions

Alternatively you can read the replacement data from two columns of a csv file as explained in my reply to the Forum post at:
www.advancedrenamer.com/forum_thread?forum_id=11652

Use the Pre batch script as written (modifying your csv file path as appropriate) and use the following main script:

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