Create, Update or delete a resource across many stacks

Hi all,

I manage more than 40 terraform stacks. Cloud provider is AWS and I use git. I have the same security-group to update for all of them. Every time I’m asked to update it and adding new rules, I have to update the 40+ terraform stacks.
I’m looking for a smart solution to update it once. Do you know such a tool to update the same resource across many terraform stacks ?
I have a similar use case for tags (add new tags or update existing tags) at the EC2 instances level or instance role to detach or attach.
