Haven't found anything like this so here goes:
How about allowing the "Select all" command to select all dimensions that show the same information. Go figure.
You could create something like that in Dynamo; here a working rough sketch proposal.
What's the end goal for this? What do you do once they're selected?
Just guessing- the point could be identifying what has turned out to be many similar values, and then convert those into a global parameter to drive them?
