New sprite sheet

When adding a new tag (definebitslossless2) in JPEXS for images is there a way i am able to rename it to(...lofiobj8...) so i can have a clean sprite sheet without piggybacking on already existing spritesheet.

I am guessing i am missing something in JPEXS.

Mike already made a tutorial on new sprite sheet

Yea found it. I guess i will have to get the AS3 client.
