for passages.
1) by the _tjust command select all objects (acad filters only the texts) and the middle input point (half)
2) select all objects and by means of ctrl+1 open the property panel.
3) the pop at the top allows me to intervene on the only circles, in whose properties I stop the radius or the diameter.
4) through the pop I move on the texts and here I change the height of the text. because by tjust I placed it in the middle of the text, the text will climb into the center of the circle (more or less, looking at the image)

If you got the desired result, I don't see what a problem can be.
you have found an alternative solution based on the possibilities available. That's the right spirit.
