I was doing some initial digging into the Sitecore PaaS version that deploys the XM1 configuration. While doing so, I noticed that there was an 'automation options' link that allowed me to view template details and parameters and there was an upload template option.

If one were to upload a custom Sitecore ARM template (say the XP1 template from Sitecore) would the Marketplace wizard be able to use it to provision? Or can you upload customized XM1 templates?
