Adding a second URL to Mobile App...

i have two mobile apps and have had one rebranded to my sites name.  In the dolphin mobile app you can add multiple domains.  I would prefer to do the same thing to avoid rebranding and resubmitting 2 additional apps when it should be just as easy to just change the domain address to sign in, is this possible?  The name of my app would apply to both sites... 

The only way I could see doing this and not submitting 2 apps or having to license 2 separate apps, is to NOT lock the app down to a single domain (main.java file). Provide your members, on both sites, the instructions on how to add the domain once they have downloaded the app.

Of course you will need to make sure that you have each feature installed at both sites. Example: if you have 'Blogs' available on the mobile app, you need to have blogs installed on both sites.
