With the Add property action, you can automatically assign predefined custom properties to cards. Please note that if the card already has the same property, its value will be overwritten. The properties with the types string, number, link, phone, email are available for selection, and this list will be expanded.
Also, it becomes possible to automatically add members to the card and move the card within the board.
Assign a responsible person, moving a card or do other available actions can be done by a command in the comments - just select the event "Comment is posted to a card" and enter the desired trigger command. If you want to limit the use of this command, use the conditions for the author of the event and card path.
