Description of problem:

Noticed that different tag categories sharing the same tags name. So can we provide the user the option of Selecting multiple tag categories and have a same tag assigned to multiple tag categories? (Screenshot attached below)

As got an idea from Gilles that in current model a tag has a one-to-one relationship with tagCategory. To support a one-to-many relationship would require changing the model.
And likely go toward a pure tagging system like used in OCP.
As the tag categories are to help organize the tags.
