Perspective MenuTree Additional props in Items

I’m driving the items prop on a perspective menuTree via database table. I’d like to store the item’s ID along with it’s other properties. I’m able to do it and the tree behaves appropriately, however a little red error icon appears in the designer telling me not to do it (i.e. ‘additional properties are not allowed’). Should I approach this a different way?
