Setting up continuous integration with AWS Amplify

We have set up continuous integration on Amplify for a regular Angular site and it works really well. However we also have another project that is used as an add in to a partner site. Currently we build the package. This creates a dist folder with everything inside it. We then have to change the name of the dist folder to the name of the addin. We zip up the addin and upload it to Amplify.

I am not sure how to repeat this process directly on Amplify. As I said it currently works for a site where we don't have to change the folder structure but not for this one.

Thanks in advance for any help.
