Cross quoting

When creating a post that quotes another quote, there's often a similar post on BlueSky / Threads too. It would be nice if I could linke those quotes in the other platforms too, so they all quote their own version.

Would be cool if it could be done automatically (find the same post on the other platforms? 🤔). But I would already be very happy if it prompted me to add a different quote URL for the other platforms, without having to turn off the sync.
