I recently bought the Premium service and have been using advanced checklists with due dates and assigning users. I have an existing board with many cards I'd like to update by adding new advanced checklists with due dates and assignees. Is there a way I can perhaps i import this data from a csv/Sheets/Excel template?
I had a look at exporting everything via csv and to perhaps reimport it (even to a new board to test out) with the added info but it doesn't look possible. Checklists weren't included in the export, just a count. In any case this likely isn't feasible as comments weren't included either in the export.
