A discussion on somewhat the same topic from long ago (2016) initially asked by me. Doesn't seem like the capability of doing this exists yet, as far as I know.
This still doesn't exist. Back then on WF2 or 3 I had to create a pattern of letters for a dial. Did it by dimension patterning a group (pattern as a place holder), Unpatterning and then changing the values. Later on, created a parameter & relation for the instances. I forgot how I did it.
