Premiere Pro Timeline Marker Duration Handles — Is There a Way to Adjust Them Directly on the Timeline Without Moving the Clip?

I’m trying to adjust the duration of markers directly in the timeline, specifically markers that already have a duration set (the long rectangular “flag” style markers).

My workflow is very timeline-based. I’m editing interviews and documentary material and dropping a lot of duration markers as I go. I’d love to be able to quickly trim the start/end of a marker right there in the sequence, without having to open the clip in source monitor to adjust. 

The issue:

When, in the timeline, I carefully move my mouse over the little end handles of the marker and try to drag them, Premiere grabs and moves the clip itself instead of adjusting the marker duration.

Because of this, I’ve been forced to:

* Match Frame
* Open the clip in Source Monitor
* Find the marker there
* Click/drag to adjust the duration from there (or double click to open the marker dialog window to adjust from there) 

It works, but it feels really cumbersome at scale, especially considering I’m currently exclusively creating clip markers from within a stringout sequence.

Questions:

1. Is there actually a reliable way to drag and adjust duration marker handles directly in the timeline?
2. Is there some modifier key, selection trick, or preference setting that makes this easier?
3. Are clip markers and sequence markers handled differently in this regard?
4. Is there a way to temporarily prioritize marker selection over clip movement?

Thanks folks, hoping there’s a smoother workflow here that I’m missing.
