Migrating Lemmy blocks to Piefed?

Is there a tool that automates transferring of blocks from a Lemmy account to a Piefed account? I'm one of those people that curates All and have thousands of blocked communities so it's not feasible to manually transfer that.

I tried Interstellar's account migration feature but the dev confirmed it's mainly for Lemmy to Lemmy at the moment. But they are still working on it so hopefully Piefed will be in the mix in the future.
