Use via variant with auto via or via stack?

On the technology I am using the default via width for the top metal is not DRC clean for our application.

I figured I could make a via variant to solve this.

The issue is that once a variant is made, its rows and columns are fixed e.g. if I make a variant and leave the rows and columns at 1x1, every array I make using the variant will be fixed at a size of 1x1.

This was asked two years ago but there was no real solution given.

Any ideas?
