As a company, we try to use the Model Items tool to pull dimensions, etc. into the drawing as much as possible.  With regard to pulled in diameters, I have noticed that RMB'ing on a specific diameter, the option to make it a Linear Diameter (Display Options), will sometimes be available, but sometimes not.  I think it has to do with whether the diameter was created using a center line in the sketch, but haven't confirmed this.  Does anyone else recognize this?  Is it publicized somewhere as so, and I have missed it, or is it rarely used by so many that no-one else has an issue?   I have searched through the forum, but haven't been able to find the same question from anyone else.
