ESS OSA Add new element

Hello all,

I've created a dynamic template where appraisers can add new elements to the template. These elements belong to the Qualifications catalog.

When an appraisal is made via Portals and the "Add new element" option is clicked a selection screen appears with the whole Qualifications catalog in a list format.

Is there anyway to modify the appearance of this selection screen. My requirements are that the appraiser should only be able to select the qualifications belonging to a specific Qualification Group.

Thank you in advance.
