Expand the number of issue types beyond 4

In order to facilitate more issue approvals with conditional approval paths it would prove really usful to have more than 4 types available. As we now have a number of request types being approved through Workfront, some of which require bespoke issue types to facilitate variable approval paths, this would all Workfront to be expanded across more areas of our business. As things stand we are constrained by the max number of 4.
