POSSIBLE WORKAROUND... Depending on what you are trying to do, I may have found a solution. It helped me, at least. Your mileage may vary, and I think a "Select All Across Pages" would be helpful—especially if you could filter it to types of objects.
Anyway, I was able to use the "Find/Change" dialog to easily FIND all TEXT frames that had a particular character style applied ("none" in this case) and CHANGE them to the desired character style. This allowed me to change the font style, color, size, etc. if no style was applied.
Looking at the Find/Change dialog, it seems like you can also FIND/CHANGE based on OBJECT styles (and now even by COLOR) and do something similar.
This requires finding and identifying your target(s) in some way and using styles to make the changes. However, it saved me a bunch of time compared to manually selecting a single text frame on 62 different pages.
Apologies if someone else already suggested this.
