Is it possible to run a script when the plan branch deletion is executed?

[A V]

We have a plan which automatically deletes branches

• after 7 days if the branch has been deleted from the repo, or
• after 30 days if no commits has been made.

Is it possible that when this automatically branch deletion is made, to also run a script? We basically want to run a script that cleans up the cloud environment when the branch is deleted by Bamboo. 

Any advice is much appreciated, thanks.
