On a similar topic, is this possible with Signal or iMessage? I have an incomplete archive on my phone due to data loss but my iPad has a continuous record. I would love to get it synced to the phone.

I made a guide for doing this with Signal using Frida if you can jailbreak. https://github.com/hsorbo/signal-backup-ios

This [0] (I made this) will let you get your messages out into Markdown/HTML + attachments, but I'm pretty sure there's no way to get them back onto your phone yet.
