Hi Jochen

This support will be given in Orlando. We are adding support to test UI formattor/macros within a form via 'Custom UI' steps. I believe the UI shown are part of a Form (sc_request etc.). 

Orlando EA/RTP is starting from January. More details here: https://hi.service-now.com/kb_view.do?sysparm_article=KB0635446
