MMF 2 - Cannot Set Focus to Edit Mask Object

I'm in an edit field and I press the tab key. Because I cannot just tab from the edit object to the mask edit object, I set up an event of:

If "edit object has focus" and "tab key is pressed" then
"set focus to mask edit object".

However, I have no option with the mask edit object to "set the focus". I can "set the data", "set the font color", "set the font background", etc... but no "set the focus".

Is this an error of the object or a inconsistent interface? In the action area, I can select "Does object have focus" but no "Set the focus" in the condition area.

I would say a missing feature on the object.

That object was made by a person outside Clickteam so I don't know if it can be updated to have those functions.
