Increased Contributor limits

Contributor licenses have considerably less restrictions than light licenses and allows our company to partner with some of our external partners on marketing campaigns without having to spend the resources to onboard them in Admin Console and our companies SSO.  Unfortunately the 7 interactions per month is too restricting.  We feel it would be beneficial if there is a way to expand that interaction limit.  

The following are a couple of options 

• Assign limited interactions to a group/team in Workfront instead of an individual.  So it can be used across profiles depending on the external partners needs. 
• Add the ability for clients to negotiate increasing the limit in their contracts.  Maybe treat it as another tier with the licenses.
