How can I downgrade an exported Layout/Buildingblocks

I have a layout that I would like to use in a different project. I’ve exported it, but i cant open it in 7.18 because it has been made in 7.22 I could recreate the whole layout with classes and containers, but that doesnt seem like a very efficient way of doing things. is there an easy way to downgrade exported files (would also be for buildingblocks)?
