I have a custom field option currently in my organization’s library, and I am trying to determine if there is a way to change the field type that is currently selected. Right now, the field type is a single-select option. Moving forward, I would like that field to be multi-select. Is there a way to change that? I have tried editing the field, as I am the owner of this particular custom field, but it does not allow me to modify it. Would I have to delete this custom field from our library and recreate it? It is currently being used in 16 different projects & portfolios, so I am hesitant to delete it.
