That downloads from a library of profiles managed by SkyDemon. It would need someone from SkyDemon to add the Bulldog to that list.
To be quite honest, it takes about 10 minutes to create an aircraft definition from the details in the POH - we've probably spent more time discussing this now than it would have taken for you to create your own!
If you re-use someone else's, it may not be correct for your particular airframe anyway - this is especially true for things like the Bulldog.
