Custom report with more dimensions?

I tried to search for this but couldn’t find any existing posts:

Is there any way to add more than 3 dimensions to a custom report? Can it be configured somewhere?

We depend on a custom dimension for most reports. That means there are only 2 “slots” left for event dimensions. So we have to choose if we want the category and action, or action and name, for example – never category + action + name at the same time.

This is becoming a bit of an issue for us, so any help/ideas would be much appreciated!
