Mcafee's vision is a bit behind at the moment for its EMM product. This should be a quick feature request that might help them keep allot of customers. F5s are too big to ignore.
Mobileconfig, as you pointed out, is the best way to get any yet unincorporated features to work. The best way to submit a product enhancement request is here: https://kc.mcafee.com/corporate/index?page=content&id=KB60021
