Can I use a Rise Javascript block to send a custom bookmark location to the LMS

I would like to do a Rise course with 4 separate paths, ending in a Storyline block which sets course completion.

I would use a Button Stack Block to send them down one of the four paths, which would each terminate in a Button Block that would send them to the end location with the Storyline course completion block.

The client would like to track which path they chose, and I am hoping to use the  Javascript block to send a custom bookmark to be recorded in the LMS when they enter the path via something like ("cmi.location", currentLocation).

Is this possible?  The course would be output in SCORM 2004.

The other way I could think of doing it would be to have a quiz question at the end of each path, the wording of which would indicate which path they chose; however I would be tracking on the Storyline block, not on quiz completion, so I don't know if the quiz info would get recorded.

Any help greatly appreciated!
