multiple entity selection box

Barbara Mayrleitner

A new object would be great - a kind of container where it's possible adding more than one entity for selection.
with all current available selection-objects it's only possible defining one entity.

we do have currently screens with more than 20 selection-entities - and we are grouping the selectors via panels... but this causes a lot of objects.. 

so it would be easier for structuring more entities in a own object - than creating for each a selector, moving each single object on the right place etc... it can look like the attached picture at least
