Yes. There’s a discussion here of how to do so: https://discussions.scouting.org/t/two-mids/440510/3
After linking the two BSA MIDs, and setting the “without training” MID as primary (I think), it takes 24-ish hours to “roll over” to the primary account. I think you have to be careful not to open Scoutbook/SB+ while the primary MIDs are “swapped”, since that can (I think) generate another Scoutbook account.
This part is a bit more challenging. None of the systems really handle scouts/scouters concurrently registered in multiple councils, at least not well. I’d defer to one of the SUAC folks to give a more detailed explanation of what does and doesn’t work, and what pitfalls there might be. I’m not sure there’s a way around having multiple Scoutbook accounts when actively registered in multiple councils, but I could be wrong.
