Allow subdomain variations in presentation

[fcisio]

Hi, I'm using the presentation editor and it seems I have a use case that is not yet supported.

My project has both languages and markets.
https://<market>.domain.com/<language>/pathname

The languages work fine as they are simple path prefixes. But the markets being subdomains is what causes issues.

When inside the editor and navigating to a specific subdomain, I get many obscure errors that don't provide much relevant context.
I do know it's not a DNS or CORS issue.

Describe the solution you'd like

I think the solution would be to add some more options in the presentationTool() plugin. Perhaps a allowedSubdomains array?
If subdomains are defined, there could be a dropdown in the editor to select them.

Describe alternatives you've considered

I have considered implementing alternate logic to pull market data via URL query params, but that's a bit too hacky to my taste.
