Default Sync X: Changing between external and internal video reference

tl;dr: How can I have an external video card being locked to the internal video ref generator of the Sync X when using NOT PAL, while at the same time having both the Sync X AND the video card being locked to external video reference when working on PAL projects, all without recabling?

Hey all,
we have several studios with HDX and Sync X devices.
Since we're part of a bigger broadcast/post facility with a digital audio router, we normally sync to incoming PAL blackburst.
This is all working fine for 25fps projects.

We're working on a lot of NTSC and 23.98 projects (with some true 24 and HFR projects mixed in).

For this scenario I'd like to switch to internal video ref generation by the Sync X, feeding the Aja Kona cards with ref from the Sync X to keep the system frame edge aligned.

Problem is: Just one of the scenarios works, but not both of them.

The Kona card is only seeing reference in when the video ref is being generated by the Sync X, not when the Sync X is using external video ref.

That only works when using the reference output BNC connector to connect the Aja Kona card to the Sync X, but then it only mirrors the PAL blackburst house reference.

I cannot every time change the cabling.
I would expect the gen ref output to simply mirror the external ref input when external source is selected.

Is this somehow possible?

Thanks!
