Is there a way in a Butler rule to reference another board based on user?

[Graf Reiner]

On Trigger Card [Button Press],

Create new Card on {username}.Issues.{cardname}.

I have a Board called Triage, which is a group/shared board. On that board, new cards get created by a Slack rule. I have multiple users/techs who monitor that board. What I am trying to accomplish is. Have a button on the newly created card that they can click. When they click it, an identical card gets created on their "personal" Issues board. My problem is, I dont know how to specify the board to create the new card on, based on the user who clicked the button.

Try using a lookup list where cardname is member username and description is board name then use {foundcarddescription} as the board name when you copy the card.
