Deploy a monorepo's subdirectory on AWS CodeDeploy?

Question

I have a monorepo like so:

my-monorepo:
  - services/
    - appspec.yml
    - ...
  - website/
    - appspec.yml
    - ...

I want to deploy the website, but not services. How can I do this using AWS CodeDeploy?

It would be best to configure CodeDeploy to use website/appspec.yml, however I cannot see how to do this. Any help with this is appreciated.

Thanks in advance.
