Please Help - Trying to Design Column Triggers in Task Management – Help:)

Hi, I am trying to wrap my head around adding action triggers to columns in Cogency's Task Management System. The basic idea is when an Issue ( aka Card ) is dropped on a column, some action needs to run.

Here is my current sketch of the process. https://cogency.cogency.io/proxy/jzB

Am I thinking correctly about this problem? Are there better ways of solving it?

Any help/ thoughts are appreciated !!!

PS: I am doing the design in real-time so anyone is welcome to watch

Thanks, --Linda
