Adding More files- continue the sequence

So I rename a bunch of files in a folder into a proper sequence, such as: Orchids_001, Orchids_002, etc. Later on, when I add more files, how can I get that same sequence to continue? If I leave off on _067, the next time I want to start with _068, but AR wants to start over from _001, with the result that there are conflicts. Maybe I'm doing it wrong?
This is my workflow. I use two batch steps: Remove, which removes the old filename (such as IMG_1234) and puts in a 3 digit number sequence _001, etc. Then I add another step, New Name, to put a name before that sequence, such as "Orchids". So the result is "Orchids_001, etc. But then when I add more files to the same folder, and try to run the same steps, AR starts over from _001, instead of starting where the last sequence ended.

Generally, you would do your two steps in 1:

With

IMG_1234
IMG_1357
IMG_2468

you would use one New Name method:

Orchids_<Inc Nr:001>

to give

Orchids_001
Orchids_002
Orchids_003

The form Nr:001 forces the 00x format. See https://www.advancedrenamer.com/user_guide/tags_ default

If later, you wish to start at 68, use <Inc Nr:068>
