Autochain only naked edges using Blendsrf?

I’m trying to blend two surfaces with very complex edges, is there a function which allows me to autochain only naked edges? it is taking forever to select the edges I need, I’m hoping there is an option for this to save an extremely long and laborious process.

Hi Martin - no- can you try MergeAllEdges and then select one at a time (should be far fewer) or use Next on the command line?
