In Default Booking Form settings I can prefill fields value with user profile data (Data Mapping).
Ok, it works well for username, complete name and email.
But I can't use Joomla user custom fields. It's so relevant for us...

e.g. For each user I have a field named "Company" ("Azienda" in italian). I want to prefill a booking field with that value, but it's impossible.

Could you implement this feature? I think it would be a significative improvement useful for lot of customers.

Best regards
