I have been trying out v. 3's new custom metadata options, and I was hoping to be able to create a type that would constrain the choices, like "list" – but allow multiple selections, like checkboxes.
- Reader 1
- Reader 2
...where Readers 1 & 2 would be checked, but Reader 3 wouldn't.
I know I can already add multiple checkbox items, but I would like to group related checkbox items, so another group, for example might be for "Drafts sent to". I know I could make a "text" type custom metadata and just add entries, but I'd rather be able to check off recurring items than have to re-type them for every document. If I make such items (like reader names) a "list" type, I'm limited to selecting only one item from the list, but allowing multiple selections from a list type would solve the same problem a slightly different way.
I think it's just not possible (and have scoured the manual and forums), but before I go submitting it as a feature request, can anyone tell me how to do it if I'm wrong?
