Ok, let me try to reword them since I made a little error in calling tags sub categories.

So let’s have Discuss 1-4 = Category 1-4  
and A-F will be for [tags](https://meta.discourse.org/t/admin-guide-to-tags-in-discourse/121041)

So let’s pretend the table is blank. I create a new topic under Category 1 and add an ‘A’ tag. Now the table should show a single topic next to Category 1 and under ‘A’ :

In the event that I remove tag ‘A’ and assign tag ‘C’ it will update the table accordingly.

Is there a way to do this?
