That will be a showstopper for our applications due to our process flow.
Builds are compiled on our developer machines, each compile is sent to testing, then to staging, then to production.
(We currently only have 1 copy due to cost, so I'm only developer using this and I'm still pushing our administration to use a build server so we can use dev licenses, but we are limited due to our source control (Vault), which doesn't support many build servers that I've found)
So we would need a single web server, which is unlikely possible to be approved.
The reason for this is, each compile may or may not have bug fixes, can't 100% guarantee that what compile will not fail testing.
I will just wait to see if you guys implement a way to dynamically set the URL.
