Company Branding on URL

As a new user to DripJobs, I am enjoying the streamlined features and functionality of the system.

I would really like to see a custom branding option, (i.e. When customers click on their proposal it would show app.COMPANYNAME.com instead of app.dripjobs.com).

I don't mind the Powered by DripJobs at the footer of the emails, as it does show reference to this amazing product, but being able to direct a customer into their Portal with my company branding would be beneficial.
