Extended overlay on open parenthesis when referencing a class method?

I wonder if there is any way of manually extending the shown contents of the small help overlay that MATLAB produces when I open a parenthesis after a function name to suggest me the name and order of its input arguments. I wrote a class of which almost all methods are non-static, and therefore require the class object as the first input argument. Unfortunately this leads to the help overlay only referencing the class object and ellipsis right after, although the method actually contains multiple input arguments:

I find that utterly irritating to users, and counterintuitive, since I don't have to pass the class object into the method myself. So there is no information on the actually required input arguments whatsoever. Is there any way to maybe optimize the method definitions or a special setting in the MATLAB IDE to show a little more here?

Btw. pressing the "More Help" link in the overlay is not an option for me here.
