It’s a very common activity to extend the profile screen with screen logical attributes but they are not supported with Bulk Loader. A little discussion has already been done on the community opened ("https://communities.ca.com/thread/241698733") which asks the support of screen logical attributes with Bulk Loader but there is no plan to add this useful feature in the future release of Identity Manager.
Do you know if the Enhancement Request has been evaluated?
I think this idea should be evaluated again.
Thank you and Regards,
