Trello Integration: Specify Conditions

Hi,

It would help if we could specify conditions when setting up Trello Integration. For example, only integrate from the list "To Do". At the moment, all lists are integrated. 

A similar concept is already supported on Trello Integration Setup > Import Record. (Please find attachment). User can flexibly specify Trello search string like is:open. This gives me hope that both UI and technology is nearly ready to support similar limiting search specifications for continuous integration.

Thank you,
Marian
