Data Classification on boards


I’m looking for a way to add data classification/security class to boards, in a similar way as Miro does it.

A dropdown in the board description, maybe? And make it part of the board creation dialogue (with admin option to make it default or not).

That’d be so awesome!
Our organisation is doing security certifications, like ISO 27001 and NIS 2, and classing of information assets in this way is essential.
It could be a deal breaker for us.
