Reordering Taxiway Parking?

The order parking spots are listed in the UI seems to me to depend on the Index value, is that correct? And there doesn’t appear to be any way to change that in devmode, requiring editing the XML to change the number, which will require changing all the subsequent numbers and all the Taxiway Paths that reference them, likely leading to a mess of spaghetti? Or did I miss something, and there is a way to change this in the editor?

Thanks for any help.
