Link LID to Attendee profile

(8777)

Requesting that you add the capability to LTO to enable customers to select their preferred language and have that language (LID) written to their profile. This would be available both when a customer creates their profile directly in LTO, as well as after their profile has been created and the customer wants to change their preferred language and have it written to their profile. Today, we can allow a customer to change their VIEWING language - but that does not get written to their profile.
