Can you explain this?
The ultimate goal is to create a Kanban report that would be based on the multiple-choice (in T1) field that would also update the record in the other table (T2).
I have a feeling that you are really asking that you want to use a Kanban report, but at present it only supports multiple choice fields.
if that is the case, then you would need to set up an Automation to update the field on your record for [Related Choice] to mirror the change in the multiple choice field which happens when the boxes are dragged around.
