This sounds like a perfect candidate for a feature request. You should submit it to Adobe: https://www.adobe.com/go/wish_de
Adobe’s improved their markers quite a bit over the last view releases, but there’s still a few things to go. In my workflow, I use markers that extend over the period of time something occurred in the footage. I love this feature because I can name the marker and see instantly in the timeline or preview monitor where something happened and set my in and out points right where I need them. However, the one big annoyance with this is that Premiere won’t snap to the ends of the extended markers in the preview panel, whether holding shift and dragging with the mouse or using the shift+m shortcut. It seems odd to me that such a simple feature wouldn’t be in there, since you can snap to the ends of markers just fine in the timeline panel, just not in the preview monitor. Just one more feature to request I guess.
Hopefully Adobe comes through for us Alex,
