Controlling navigation in Rise with Storyline audio block

I am updating a compliance course in rise and need it to be a minimum of 2 hours long per state statute. Given that there is no way to require audio to be played through in rise before marking a section complete (at least that I can find), my proposed work-around is to create the audio blocks in storyline and restrict navigation until the audio block is completed, then embed the storyline audio block in the rise course. Will this work? Or is there a better way to do this? (We have been restricting navigation through our lms but this is creating lags between sections and every time we update the lms software we have to reinsert the code.)
