making plugin insert route as mono or stereo like in nuendo

i write here before go to feature request with this.
in nuendo 5 i can open a stereo FX track, insert there a reverb plugin open its GUI then change the plugin to be mono(not possible with C7) and route it to the left only… then i insert another reverb plugin to the same FX track make that reverb plugin mono and route it to the right…
this way i can save a track preset of stereo reverb of my liking in nuendo…
in C7 i can’t find a way to make a plugin insert as mono with stereo FX track.

sounds cool, I don’t know how to do that without extra busses or separete L + R channels.
