You'll want to keep an eye on Qodana[0] which when combined with ReviewDog[1] (and some glue script since Qodana has its own snowflake output JSON that RD doesn't read natively; engineering!) can offer suggested changes on MR/PR platforms which support such a thing [2]

I have the first two working together but not the last part yet, and Qodana is for sure a moving target but is what I've been praying for them to do for years now
