Currently the only valid locations for a board are:

• classic project
• personal

If I'd like to have more than one board for a next gen project I'd need to either migrate to a classic one (overkill) or have it defined on my personal space (which is strange for a board that's going to be used by the team).

I'd like to be able to either have secondary boards on next gen projects or be able to move them to the team space instead of the personal one.
