@Rellwood - if you want to do it, here's how I would do it

Backup your library - you'll understand why in a minute, see this ==>> How do I backup calibre?. Close calibre first of course.

Create an Admin Tags column thus;



Restart calibre - you should get a Restart calibre now option after creating the column and clicking the Apply button.

First select all your books (ctrl/a) in the book list with no active VL or search. Copy the existing Tags column to the new Admin Tags column with Bulk Metadata Edit thus (Note the warning at the top of the dialogue box ) :



Now you need to remove the 'admin tag' values from the Tags column, and the 'content tag' values from the Admin Tags column. I would do that via the Manage <categories) feature. In the left sidebar (Tag Browser) right click the Tags heading and you'll get something like this



Remove the 'admin tag values' - multiple items can be selected.

Now do the same thing for the Admin Tags by removing the 'content tag values'

Perhaps the single Admin Tags column might be sufficient. You could group source, location, and status values using first character - e.g. '!' for sources, '#' for locations and '@'for status - I call this bang, crunch, and snail tagging.

You can edit the values in the Manage Admin Tags dialogue by hitting F2 on Tag column cells.

Now you should have two columns each serving there own specific purpose.

I come from the school that says don't overload the same column/field/property/attribute... whatever, with different purposes.
