I wished it used one too. In the meantime, the best thing to do is to install mods that don't use the patcher first, then install ones that do use the patcher. For conflicts with .2da files from mods that don't use the patcher, you'll have to either manually edit the 2da files with KotOR Tool or with stoffe's 2da Plugin for MS Excel. I don't have the links for these handy; just search a bit, you'll find 'em (for stoffe's plugin, the link is in her sig). Tutorials can also be found here on these forums.
Your other alternative between editing 2da's is just choosing to use one or the other.
