Interiors entity list, and using entity as place holder..

Ok, great to get back to the scene here again, and wicked to see that GTKRadiant has gone GPL.
Which is why I need an entity list and their accepted params, I got most of them, including lights, set up in an entity list for gtkradiant, but theirs a few I need help with, say targets and pathed interiors.
For the moment the entity list is rather complete but a full list would be nice to work from (and also something incredibly hard to find).

Other thing... Is it possible to, say place a model in the interior (in gtkradiant/worldcraft/etc), have the brush editor store the model location, size and direction in the map file, convert to dif, then have the engine, place the appropiate model in the place saved?
Reason I ask that, is it would save a heck of a lot of time and speed up the design flow.

I really don't know how entitys are handled in the engine so can't really trawl through the code myself and suss it out, I'm trying though, help would be nice too...
