That would require the program "knowing" how you numbered the original images. Consider, for example, someone for whom:
MONS1
MONS2
MONS3
MONS4
MONS5
MONS6
MONS7
MONS8
MONS9
MONS10
was meant to turn out like
MONSA1
MONSB1
MONSC1
MONSD1
...
And what about MONSA2A8 versus MONSA2, MONSA8 (or any other combinations like MONSA2C8 etc)
and what about MONSA0?
I suspect there are just too many unknowns here unless you create your images to a known, predetermined numbering scheme (and even then, the variation in final naming would still be a problem). So, that really just begs the question, why not call the name files using their intended sprite names in the first place (that's what I do when I'm working on a sprite set). No need for renaming, because I gave them a Doom compatible name from the outset.
In saying all of that, who knows, you might be able to come up with something cunning using a dedicated renaming program such as
Rename Master - a useful program to have around even if it doesn't turn out to be helpful here.
