Reference data of another Grist document

Hi!

In many cases we need reference data that are the same in all Workspaces of a same Site. For the moment we duplicate each time that reference data in each Workspace, so we have to maintain this master data everywhere. An exemple : the list of French cities. We need it in a lot of Workspaces and it's everytime the same list.

It would be great to have a space in the left panel with these master data directly in the root Site.

We imagine that it must not be an easy feature, but it would be very useful for us

(Maybe there is already an issue that we can't find)
