Get Host Element - Wall openings

Just did a couple of openings in the wall using this plugin:

Question - been having a hard time trying to copy some parameters from the walls, as they are not the host id. Each planer has delivered their own openings and I just created a container file out of the received ifcs.

Hence the created generic models do not have their host element on the wall, but on the imported boxes from each planer.

How can I copy parameters from the wall and what can I use instead of a host ID? Can I try to check in Dynamo which walls overlap with the voids and then pick the parameters from there?

Thanks for any support!
