More than two Eagle skins?

[Eagle Driver]

I'm having some trouble installing Eagle skins here. I've got an F-15 ACTIVE skin set in the #1 US spot, and had an Oregon ANG one in the #2. The OANG one just replaced the fin, leaving the default... everything else, and it worked fine. BUT, I love both of these and all the skins at lockonfiles replace the #1 or #2 skins, and that's bad. So, how do I set them up to go in #3, #4, #5, etc? I had a hunch, because one which went to #2 had a bunch of 2's in the file names (YaddaYadda-DEF-2) and so I replaced all the twos with threes, then sent them into Temptextures. It seemed to work fine, the ACTIVE, ANG, and Desert (new) skin worked great in #1, #2, and #3, but a bunch of the other ones had the default grey tailfins but everything else was desert. Can someone explain how to monkey with it so I get all the skins working right?

There are few slots sharing same fuselage/wing skins and only tail is unique. I think overall there are only maybe 3 main fuselage/wing skins and from those other skin sets are derived by just changing different tail skins.

Okay, so let's say I want to edit those default F-15 skins that came with LO, where can I find them and is it even possible to edit them at all?
