Dynamically add fields to input dialog

Question

Is it possible to somehow add input fields to an input dialog (inputdlg()) in MATLAB when a specific event occurs, e.g. the user types in a certain value in one of the existing fields...? Or is there any other 'hacky' way to achieve this so that the user doesn't have to click "OK" and I have to code to reopen another input dialog which contains more input fields.. Thanks!
