Hard panning master send FX?

Hi, in Analog Four Amp settings I’ve set hard pan to the left for voice T1 and T2, and hard pan to the right for voice T3 and T4. I’ve routed Main Out L to one channel of the mixer, and Main Out R to another one. Its because I just want to have a “mono” signal going through Main Out and ability to use Send FX. I cannot however hard pan send fx. It it possible somehow? If I add for example chorus on T1 I can still hear it out of both main outputs. I want to have it in mono, just on the channel that belongs to each T voice
