Can start using CI/CD with existing resources?

Question

Hi,
I'm fairly new to AWS and have created a solution the consists of 4 API endpoints, one S3 bucket, 6-7 lamda functions and 2 step functions. I use Git in VS code, but deploy everything with the AWS extension in VS code.

I'd like to start using SAM, Github actions and separate my dev,test, prod with Stacks. I see that Cloud Formation have a solution to import existing resources, but I can't find anything about SAM.

Is there a way I can merge my solution into SAM without starting from a blank template and manually create it?

AWS SAM cannot import existing resources from the management console.
