Form field with a list of all email assets in a campaign

Is there a way to populate a form drop down list with all emails in a certain campaign? for example I want to build a Landing Page that would allow a sales person to enter a leads name, email address and campaign code, (when he enters the campaign code, a list of emails within that campaign would appear as a selection option). Once all information is entered, the campaign will send a email to that specific lead. This enabling a sales rep to send a new customer a copy of a previously sent sales email easily.
