Changing numbering label

Greetings all. I have a project that will have over 4000 files that need labeling individually , I have titled the file with a prefix and audacity can automatically number them after, however, I may need to remove the hyphen that is in front ton the number digits is that possible to alter ?

Example 1
This is what the file name looks it look like now

section_-08.wav

What is needed is

section_08.wv

this small hyphen/ dash - can it be removed some how??

Are all of the labels in one label track, or do you have multiple label tracks?
