Adding Tags to Categories

Hi,
I'm using Joomla 3.9.2 and JEM 2.2.3 for a community website.
I've successfully tagged various Joomla articles (lets use 'Music' as an example).
What I'd like to do is tag relevant JEM categories with 'Music' tag so that the normal Joomla articles and tagged JEM categories are searced and displayed.
Is there any 'simple' way to do this?

Until now not. But you're invited to find a solution and to share the result in this forum.
