How to control a subrack parameter via Device Parameter Control ?

Hi everyone,

I’m struggling with a limitation I can’t seem to get around using.

Here’s the situation:
I have a main rack in which all 16 macro controls are already assigned. Inside this rack, I have one or more subracks that contain devices I would like to control via Device Parameter Control.

However, since the 16 macro slots are fully occupied, I can’t map any additional parameters to the main rack, which means the subrack parameters are no longer accessible. I’ve tried using Chain Targeting, hoping I could point directly to a specific chain containing the subracks, but I haven’t been able to access the desired parameters.

Is there a way—perhaps with a Remotify script or workaround—to control parameters inside a subrack in this kind of setup?
Thanks in advance for your help!
