Url Parameters For Transfer

Hi ,
Thank you for the useful plugin first . Actually I need option called url parameter for transfer , For example if i use the link – https://example.com/transfer/?transfer=example@gmail.com . As you I have used some extra lines in the link (?transfer=example@gmail.com) If i provide this link to the customer , in the transfer page transfer email or user should be selected automatically which is provided in the link (?transfer=example@gmail.com). Thank you
