I want to set the Control Type of a variable to "UserControlObject" in WorkWithPlus

Question

I want to set the variable Control Type to the "UserControlObject" I created, why is it not in the list with WorkWithPlus properties?

Will it appear on the list with the versionup of WorkWithPlus?

Control Type of variable can be changed from WebForm.

I need the same list as Genexus WebForm properties.
