Hello dauster, you can split assigns by clicking in the dropdown close to an assignment variable. This will help you in the scenario you described. For more details check the image below.

Also, you can later merge multiple assigns. Simply by selecting both and doing right-click and then "Merge Assigns".

Hope this helped.
Thank you for the idea. Keep sending ideas! :)
