TGB + MipMapping?

I was wondering if TGB supported mipmapping (and maybe trilinear filtering...) out of the box. Specifically, user-generated mipmaps. Why I'm asking is I'm working on a game and I'd like to be able to zoom in and out during gameplay and with just the smooth (bilinear, I'm assuming) filtering set for my images this ends up looking pretty bad. (flickering details and so on)

Thanks for any help!

P.S.: TGB rocks hardcore. Can't wait to get ahold of an Xbox360 and play around with TGBX!
