Recently I need to assign quite a few HSQC spectra by comparing with known assignments. The assignments are done through the atom assignment window. Id like to modify the default program so that once I make a selection of an amide proton, the amide nitrogen of the same residue will be assigned. This will save the trouble to make two assignments and prevent mistakes of wrong selections. My question is whether this function is written in an accessible python extension or compiled in the core program.

Thanks.
