I've looked at Help and Forum and can't seem to find a way to add a locator to several or all of the clips in the timeline (same position) simultaneously.  Maybe my search terms are inadequate...

If I highlight all clips and try it, locator only shows up on topmost clip.  Then, the only thing to do is to add locator, then dehighlight that clip, and so on.

Trying to set some sync points on long form project.  Thanks.

Strangely, if I highlight all tracks of a clip, and each already has in sync locators, a single delete eliminates them all.

The reverse, highlight all, and insert a locator, doesn't seem to work.  I can only do one track of a clip at a time.
