Is your feature request related to a problem? Please describe.

Backports are painful and take alot of time especially with multiple repos.

Describe the solution you'd like

In general it would be nice to have as much of the backport process automated. For this first chunk of effort we propose starting with a PR tag that will auto cherry pick and open Backport PRs based on some tag. This is similar to what is in place for isitio.
