Rinominate file for extra frames

[Ally]

I use these scripts to enhance the character frames:


https://galvs-scripts.com/galvs-character-animations/


and


http://rmrk.net/index.php/topic,46822.0.html



We created this character to add it as an enemy in an event.
But I can not figure out how to rename the file for have both the walking animation, both the idle animation...


This is the character in question:





How must rename the file?


The first 4 frames are those of idle poses, the others are the walking frames...
