open poly~ voice in bpatcher

hello list,

for a jitter project i want to open a poly voice inside a bpatcher.
at the end i have about 100voices and i want to be able to load the "voice patcher" inside a bpatcher to adjust the property of the voice.

without bpatcher it is possible, but not very comfortable.
so i have to care about the patcher windows and i have window bar ....
i have a patcher attached to demonstrate the problem

does anybody has a hint for me to open a voice inside a bpatcher or another workaround ?
i also tried pcontrol without success :-(

thanks in advance,
yonfell
