Can I create an initial AG & AG Listener for a single Server / Database and Add the Other Replicas after?

When creating a new Availability Group it would be nice to first create the database on what will be the Primary server and immediately create the Availability Group listener so that Apps can connect immediately with what will be the final connection string. e.g. MyDbAGListener.domain.com

Then I can work to prepare the replicas and add them to the AG as they become available but my Apps are all running with the correct Conn string.

I can;t seem to do this via the Wizard but was wondering if this sequence can be done in TSQL ?

Thanks
