Can you change format values in smart dimensions like you can in callout properties?
For example I want a hole dia to be .xxx but the the depth only needs to be .xx
I think You have to use format styles therefore!
Create them so You can use them per easy selection in 3D
If You are talking about drafts, then I would prefer the dimension type as selection method.
Use "feature legend" for holes where You clearly can define how they should look like.
And in options - dimensions You can define which type should use which format style.
I will try to make some pictures when back in the office with a SE computer running
