Is there a way to import BTT2 presets into BTT3?

I'm a BTT2 customer and had to update one of my Macs to Catalina (from High Sierra), which means my BTT2 app didn't work anymore. I'm trying out the latest BTT, and I tried to import all my presets, but it says it's in the wrong format.

Is there a workaround? I've got lots of presets defined and it would take me a while to re-define them from scratch :frowning:
