I use a series of checklists in my cards for various repetitive tasks to ensure I'm maintaining standard processes at my place of work.
For example, for Task A, I may have several closeout tasks to do such as "email so-and-so that task is complete, save documents to hard drive, and update completed project spreadsheet"
I do lots of variants of "Task A" so I keep this to-do list in a template card. Sometimes I get overeager to mark a task as complete and move it to my "done" column once its complete, but I haven't done my closeout tasks. I want to set up a process such that my board won't let me move a card to done unless the check list is completed. This forces me to take a step back and double check that everything is actually completed. Is this possible with Trello?
