This would allow a user to create custom whiteboard templates to support internal processes and meeting types. For example, one of our internal teams performs regular retrospectives and organizes the data in a specific format each meeting. Being able to have that team create their own whiteboard and then turn that whiteboard into a reusable template would speed up the time it takes them to prepare for their meeting.
Thanks for the idea!
Workspace owners can now create a custom whiteboard template:
From Workspace settings > Document templates
From an existing whiteboard, select [...] > Save as template
