Combobox - quickcreate

From a UX perspective it would be great if the combobox would provide a quickcreate functionality similar to the quickcreate in the section "Tags" when working with user stories in Mendix Project Management.

This could be implemented

• by allowing developers to hand over the search criteria as primitive parameter to a microflow/ nanoflow when "On Enter Event" (or other events) are triggered. E.g. include boolean "Include search value as parameter" when a event is configured.
• by adding a functionality in the widget itself which can be configured to have a item/ button at the end of the result list called "Create {entered value}. Instead of selecting the item it would create a new object (matching the configuration) when clicked and fills in the selected attribute of the display value (similar to Tags in Project Management).
