Ability to select role, not user

Hello,

In the plugin I have the ability to create a field called users under the relational options. Here you can choose which roles to include.

Once added to a page, you can only select a user/s associated with that role.

Is there a way to just select the role and not a user?
e.g. selecting editor will include all users assigned to the editor role.

Any help much appreciated

Thanks
