Saving space using UV Map Edit?

[Outcast]

I've got a lot of extras with different names. How do i combine them into one extra? They each have different NiSourceTextures. I tried renaming them into one common file name but that didn't seem to work.
What am i doing wrong?

Changing the NiSourceTexture should work. Did anything at all happen when you tried it?

Ok. After double checking. I think i've found what i was doing wrong. I missed one piece! I didn't rename it. Thanks JKCarrier for confirming that what i was doing was right all along.
