Hi Jan,
Yes, it's correct, at the moment there is only one Presentation URL and you cannot have aliases for it. However, on your local dev environments you can use the same URL as on stage server - simply add this domain into your hosts file and configure IIS binding for this domain. In this case stage and all your devs will be using the same domain name.
The only difficulty would be if devs would need to actually open stage website they will need to comment out this setting in hosts file.
The other option to consider is using automatic Staging content sync but this will require some work to do, but it could be reused on other similar projects later.
