Import Open­API (OAS) into API Tools

Hello,

I came across API Tool today and I think the software is really cool!

My question: I have an API created with Swagger in OpenAPI 3.0.3.
Is it possible to import the YAML (or the JSON) file? I would just rather not have to build the complete API again in API Tools.
Of course I can also customize the necessary parts.

Many thanks in advance.

Regards
Sven
