Direct routing for redundancy system

In a professional application, we use a redundant system with two QCs and a Fretronics RSW Auto Redundancy System. So in case the main QC goes down, the redundancy manager (RM) switches automatically to the backup QC. This works using a pilot signal which goes from the RM to Return 1, through the grid out of Send 1 back to the RW. So the RM “knows” when the main QC goes down. For now, we use the last block in row 1 to make this setup possible. But that makes parallel signal processing in the top two rows impossible. The bottom two rows are in use for a DI (with cab sim) and post amp signal split. So we are pretty limited with routing now.

Here is my request:
I would like to have a global direct routing option. So any physical Input could be directly routed to any physical output.
