Duplicate groups over multiple boards at once

Hi, I understand how you can duplicate a group in a board and copy it to another board, but we work with 30-40 brands at a time and when we add a new client, they need to go onto at least half of the boards to chase up for samples etc.

So is there the functionality to copy a group in one board , but duplicate it accross many boards at the same time via tick boxes or similar, rather than duplicating and moving multiple times ?

Many thanks, Mike.
