Premiere: Faster way to “Group Clip” stills?

Question for anyone who’s done this.

In Avid I can group a bin of JPEGs/PNGs and flip through them quickly in the timeline (using the GroupClip Up/Down trick) while building creative selects. It’s a super fast way to browse stills as if they were angles.

Premiere doesn’t allow creating a Multicam Source Sequence directly from stills, so the workaround I’ve been using is:

1. Drop each still on its own track (V1, V2, V3…)
2. Select all → Nest
3. Turn the nest into a multicam
4. Flip between angles

It works, but dropping each image onto a separate track takes ages when you have a lot of stills.

Is there a faster way to auto-stack stills onto separate tracks, or another Premiere method that mimics Avid’s GroupClip flipping workflow?

Goal is simply to flip through a batch of images very quickly while building selects the same way I will do it in Avid.

Thanks
