I'm making a map that has five inset maps that display a smaller map scale where point features are more dense. I have exported my labels to annotations in the geodatabase so that I could fit the labels that maplex wouldn't draw and move things around for the final touches. I am using the same annotation layer across all the insets so my GDB isn't cluttered with multiple annotation classes.
The problem is that because these data frames use different map scales the annotations are drawing at different sizes because it is set to a single reference scale. I can't set it to 0 because it is in a geodatabase. Using Symbol Substitution changes the font size, but it doesn't scale the font to the same sizes (10pt in one data frame displays at a different size than 10pt in another data frame).
My question is: How do you display the same geodatabase annotation class in multiple data frames, with diffent scales, at the same page layout font size?
