Adding new board from issue sources resets all previously selected issues

[Virgil]

Hi community,

I'm adding a new issue source (board) to an already existing plan. Adding an additional board requires me to re-select every issue across all issue sources (boards). Is there a setting to not reset? 

Real case scenario ... Our team is following a plan, but we need to add an extra team. It would be tedious to re-select everything that was in scope.
