How do I upload a multipage site to iMIS cloud?

The iPart approach described here https://developer.imis.com/docs/developing-a-client-based-ipart, only works for SPA (single page architecture).

We have a simple site with subfolders that we want to upload. This site is HTML documentation for our JSON/ REST spec that is auto-generated from Bitbucket. Ideally, we'd want to establish a CI/CD pipeline so the documentation is output to a specified endpoint in iMIS. However, we're happy to zip it up and unzip at the specified location.

Is there a way to do that in iMIS Cloud?
