Deploy the same yml in parallel

I’m trying to deploy, in parallel, the same serverless.yml to two different profiles using the flag --aws-profile.
Unfortunately, I’m getting different exceptions on conflicting access to the directory .serverless,
mainly: no such file or directory, CodeSHA256 (..) is different from current CodeSHA256 in $LATEST (..), etc.

I tried to use the package feature (put the deploy package in a different directory per process), but it works only partially because it is still using .serverless inside the two processes which create race conditions.

Is there a way to change sls's working directory?
