I can't route a FX channel to a Group channel

I want to route a stereo lead vocal, all (in this case 3) my FX channels to a group channel which is routed to the stereo/master out, so every channel is under the same EQ and/or compression. I’m sure that there is a logical reason that I can’t route a FX ch. to a Group Ch which I can ponder later. But is there a way I can accomplish this?
Thanks Ross :cry:

The logical reason is: your are certainly creating a feedback loop / routing of any kind. The way to accomplish it is to disable the potential feedback loop.

Thanks
