Image Tagging & Yaml Configuration

I've read it's not advised to use "latest" when configuring your Container App. The action when setup using the "Continuous Deployment" pane in Azure uses the commit hash which seems advisable. But as far as I can tell you can't pass parameters to the yaml file so it needs a fixed image tag. Is there a way to use this action but also use the yaml configuration? If I exclude that during the update I get errors about the registry but if I include it the tag has to be "latest".

If they were separate build & deploy steps I could update the yaml but as it's all one piece, I'm a bit lost (well, I was lost before in docker world so this cannot be attributed to this nice action).

Thoughts?
