Please add a search box to the role allocation drop-down in the User profile. We currently have 161 roles and more will be added, so, to be able to quickly located the required role rather than scroll, scroll, scroll (or using the upload template) would be a big time saver.
While this is definitely a workaround vs. a full solve for this UX enahncement; users can actually use Ctrl + F (or Cmd + F on a Mac) to bring up the browser "find" functionality, which does let the user search through the roles list.
