I can't find a way to determine which xref needs to be reloaded if there are multiple ones being used, but a right click on the icon gives me an option to reload all of the xrefs. I don't know if it is any better than before or just different, but it seems to work. There is a variable that will take you back to the old xref manager but I can't find it at the moment. I will look some more and post it if I find it.
