Custom SPFx app on SPO: How to roll back to previous version?

Hi.

We've developed a simple SPFx app, and installed it on a couple of sites on our intranet. 

I package-solution.json I can set the app version that's used by our SPO  sites' app store.

Say I have deployed version 1.0.0, and then deploy version 1.0.1. Can I roll back to version 1.0.0 using only SPO app store? Or do I have to delete the app from the app store, and upload version 1.0.0 and re-install it on the sites?
