hi teqy. what you can do is load your subpatches into a bpatcher and then in the bpatchers inspector select open in presentation view. The bpatch will be in your parent patcher and all controls will be visible in the main patch take a look at the file below.

Hope it helps

you could make the controlers for the inside patcher, in the outside patch, and create there the presentation view interface controling from there the main patch, as well as the inside patch, or you could do what Thomas said!
