XLwings selecting item on ListBox

Question

I am trying to select items programmatically from a listbox. On VBA I will do:

Sheet1.MyListBox.Selected(0) = True

Or to deselect

Sheet1.MyListBox.Selected(0) = False

With XLwings I have been able to easily check if an item is selected by doing:

>> wb.Sheets(1).api.MyListBox.Selected(0)
True

But if I try to assign a value I get an error:

wb.Sheets(1).api.MyListBox.Selected(0) = True
  File "<ipython-input-156-9ef416a5660f>", line 1
    wb.Sheets(1).api.MyListBox.Selected(0) = True
                                                 ^
SyntaxError: can't assign to function call

Hope somebody can help.

PS: I found that if you are in Design Mode (selected on the Excel toolbar) even the first line won't work on Python for some reason!

Comment: What if ... the method was not implemented? ... use ListBox.Selected(0) = True and find it is impossible with xlwings

There is no ListBox.Selected(Int32) in the current Library. Therefore I assume it have to be implemented in xlwings to be available.
Using the .api Interface you could only use whatever is provided by the Library.
