Form "Default Value" User Meta Data

How can I pull user meta data as a default value into a GD post submission form. For instance I want to automatically insert an id number that was setup and is saved in the users profile. So the user doesn’t have to input it manually since we already have that information saved in their user profile.

I know with Gravity Forms you would use something similar to this {user:uwp_id} and include it as a placeholder. Will that work in GeoDirectory forms and if not how can I accomplish this?
