How do you add animations/ change the color palettes of monsters?

so im doing some modding in my icewind dale game, and I want to make a new animation/different color for the orc shaman whatever would be easier is fine

first of all, I noticed that even if I use EE keeper it doesn't change the color of the shaman, and with NI I can go into the bam files, but by the looks of it, I would have to do EVERY single bam and manually adjust every single color index and that would just take eons, especially since I cant even save the color index anyway ( which I find odd)

so if there is a way to be able to change colors of current animations that would be great

then second, if for some odd reason the above is impossible, I imported all the iwd 2 undead shaman bams( im going to assume that what it is, and for some reason the default IWDEE undead shaman doesn't work, it makes the creature look like a myconoid) and they all work in NI for IWD, but for the life of me I cant figure out how to attach creature animations to the bam files, if this could be done that would be great as well

so if either 2 of these can be done please let me know, thanks
