Requiring Markers to Complete before advancing

I feel the first question was completely missed since I have the same question.

However, I am in Storyline 360.
How can we ensure the marker audio completes before it is marked "visited"?

My current workaround is using pictures (sometimes with hotspots if I use an icon) instead of markers on the Base slide; and link them to layers instead. On the base slide, I set a Pause trigger once the markers appear.
On the layer, I place a non-clickable/triggered hotspot (or filled (100% transparency) shape w/out an outline so it's invisible) at the "front" of the slide (top object in the timeline) as a "Click blocker" over the marker (and any other markers - I need still the base slide to be clickable, so that property option for the layer is unchecked); timing the hotspot to end when the audio completes and allow the user to "close the content" and mark the marker as "Visited".

So my question still stands. Is there a way to require the marker audio completes before it's marked as "Visited" in Storyline 360? If not, then see my product suggestion below.

Product suggestion: Add trigger: "when media completes on marker x"
