AUTO FRAME SCRIPT REQUEST

I'm having problem with my game because the Multi Frame Script changes the animation file name, like hero . So I wanted to make a request here for someone to create a very different kind of auto frame script. Maybe it would be possible to create a script where the number of frames of animation would be inserted into it? Like this for sample:

Files inside the "Characters" folder:
name of .png file => number of frames
hero => 8
hero_ACT => 7
hero_HIT => 6
hero_SWD_01 => 6

Note: It's a script for RPG Maker XP.

Thus the file name does not change, and the script will do the organization of animation frames by file names .png written on it. Someone could create something like that?
