Key command for preset "drag to clip"??

First duplicate your sequence (in case you make a mistake...) and then you need to "flatten" the multicamera clip in your timeline.  Just select all your multicamera clips in the timelin and control click and if I remember correctly, go to multicamera and choose "flatten."  That will convert the multicamera clips to regular clips.  Select a clip in the timeline that's from the angle you want to apply the preset to and control click and choose "properties."  A window will open and at the top of the window you'll see the "file path."  The end of the file path will be the file name.  Copy that.  With the timeline active and nothing selected go to the edit menu and choose "find" and in the name field paste the file name.  All iterations of the clip should be selected in the timeline and you can drag the preset to the timeline and drop on any of the clips that are selected or as I suggested, drag the clips vertically to an empty track.  I've got that command mapped to option-uparrow so if I've created an empty track above the main video track, it becomes very simple.  Post back if you have any questions.  I've been working in non linear editing software almost since it's birth in avid, fcp1-7, premiere and davinci resolve so although it may seem simple to me, it may not be as obvious to you.

or move all the clips that need the adjustment to a higher video track and then you can select everything in that track very simply with the select track forward tool.  If all these clips are the only clips from the same source clip, you can do a find in timeline for that clip name and drag them to the higher video track...

No such keystroke.

Select multiple clips in timeline and drag preset in one go.
