Is your feature request related to a problem? Please describe.
If you want to create a enum from several enums that span several categories within the Data Type Manager, the option to do this doesn't appear if those values selected span any categories and you haven't deselected them.

Ignore categories for those kind of actions.

Describe alternatives you've considered
Scroll through your selection and deselect categories whilst making sure you don't inadvertantly lose your selection!
