Is there any way to increase the amount of term enrollment units for Summer?

I know it seems odd but Summer semester has always been my most successful and productive term because of how condensed it is and a lesser likelihood of a cumulative final. I want to take 5 3.00 credit courses, but my term limit is 14.00 credits. I'm an IT junior and will be taking at least 4 GEP/electives that are the entirely online self-paced instruction this Summer. It'll be more than doable for me to add another, but just wanted to ask if its even possible to exceed the amount of term credit limits. Thanks, just trying to graduate early.
