UI: need separators/grouping in Multi QUestion

I really like multi question action. However, I would really appreciate it there was a way to separate groups of questions on a single dialog. The simple solution could be the way Delphi menu editor works: if the text of the question consists of only dashes (you can be fancy and allow emplty lines, dashes, equal signs, undescores and asterisks:-) and no variable is assigned, then the line is treated as a visual separator, with no check box next to it, and, most importantly, no complie-time error messages...

TIA!
