Future changes to limitations for filament sensor configuration

Somethings I would like to be able to do using a basic filament runout sensor.
I'm looking into having a duet Magnetic filament sensor( M591 D0 P3 C"20.io1.in" S1) near the extruder connected to the tool board mainly for detecting precise filament movement and the other one, a Dyzen filament sensor(M591 D0 P1 C"0.io3.in" S1) that only detects filament runout as a back up sensor at the other end of the long Bowden tube. The dozuki page of limitations show that this option will not be supported. I understand that "Filament monitors must be connected to the same board as the corresponding extruder motor. This use so that the firmware can correlate the measured filament movement and the commanded extruder movement in real time." to avoid any miss reading but I just need the filament runout sensor at the other end of the Bowden tube to alert me if the filament just runs out(nothing to do with filament movement readings) that's what i would have the duet magnetic sensor for mainly. I understand the Duet magnetic sensor could do the same and i could run the Dyzen runout sensor wires to the tool board but id like to avoid having so many wires running from inside to outside the printers chamber.
If i can just configure a simple sensor to detect runout on an extruder running on a separate board that uses P1 that would be great. besides that the duet hardware and software is great. Thanks for all the help aswell.
@aprz thanks it is on the wishlist but cant comment on how soon it will be implemented. in the mean time you can use the trigger system to command a pause when the switch senses filament out.
