Custom Field to Select From Member's List - Trello
BACKGROUND
In the "Activities" field, when you add a "Comment", there is an "at" symbol (@) that displays a list of members who belong to that board. You can then select one of them. Then if you do it again, multiple users will be added.
QUESTION
Is there a way to "Clone" the "Activities" field and rename it as a custom field? Or, How to add the @ ("at") symbol to a custom field so we can select from the board members list.
GOAL
We want to be able to search (using "jump to") with the custom field name (colon) followed by the user's name, like this -- [FIELDNAME:UserName] We want the custom field to be a list of OTHER members who can be searched as secondary participants. The "Board Member(s)" are those to whom the card is "assigned". And the "Watch" button is not what we need, either.
