Print / export all backlinks/nodes in local graph at once

[pleabargain]

Things I have tried

I have tried to select more than one back link to export: no joy.

What I’m trying to do

I want to print only select parts of my notes. e.g.
Node A has five sub nodes
I want to print/ export as PDF Node A and all five sub nodes of A.

Please see video
