Potential Implementations for ssNMR

I forgot to mention, there is another minor thing, when I try to drag a NMRresidue in a NMRchain onto a NCO-1 spectrum to display the coordinate/crosshair of this N/CO-1 peak, it doesn’t know it should be the CO-1 one for the carbon dimension, only uses the CO of its own residue.

Is there a way to adjust this?
