Custom URL Shortner Features

Hi JoomUnited,
In the social backlinks extension, is the url shortner feature branded? For example, does it use bitly, tinyurl or is it domain branded?
Here is an example of domain branded...
http://www.mydomain.com/u/rewswt

Could I have my domain in the url shortner feature Or does it use a 3rd party company?

If I can not have my domain in the url shortner could you add this feature to it?

Something similar to this.....

It would be so nice to have my domain in the short url.
Thanks,
Robin
