[Plugin: Custom Post Type UI] Display when creating a post

Hi,
Plug-in is working great – thanks

One question:
When I create a post, I see a field to input a value for my custom taxonomy. For example, if I’ve got a custom taxonomy called “Roles”, I can input a role, or I can “Choose from the most used Roles”.

Is there anyway I can just list these out as checkboxes??
