Our project creates tickets on a private board. When a ticket is marked as Ready for Development, our automation rules clone it onto a client-facing board and all subsequent work is done there.
The "private" ticket is linked to the "public" one with an "is implemented by" link.
What I'd like to do is create a rule that automatically sets the "private" ticket to Done when the associated "public" ticket is, but I can't figure it out with the options in the UI. Can someone tell me whether this is possible and if so, how to go about it?
