User Problem

Currently, Trello users can add members at random or in turn with Automation when they want to add these card members to new cards created on their board. However, users would like to have the option to add all members from a card to another one or multiple cards. 

This could be helpful for these very specific workflows, where multiple card members need to be added to cards and decide who will be responsible for that particular card. 

Suggested Solutions

We should add an action "Add all members from [card or card link] to the card", allowing users to add all card members from a card to the other. 

Allow users to use the prefix trigger for {cardmemberusernames}, e.g. {triggercardmemberusernames}

Current Workarounds

There are many other ways to achieve this goal. One of them is to have an Automation command to tag all board members to new cards created in a specific list. This would trigger a notification, giving users the agency to check whether that task belongs to them. 

The other option would be to have a dedicated user responsible for each team and assign these cards to these team leads. Then, they would assess it, decide to which team that card (or task) belongs, and ask team members to review it and assign it accordingly.
