Timing questions with JavaScript

Hi all,
I'm trying to use timing questions to collect first click info (and first key press, if it's possible) and at the same time I need to randomize the questions. Because randomization breaks the link between the question and related timing question, it's impossible to record correct reaction time (I won't know which reaction time belongs to which question). Is there a way to do it with JavaScript? Maybe something I'll add to the question and in the end I'll have the first click/first key press info without adding an actual timing question?

Thank you!
