The option to allow registrants to sign up for more than one grouping during a single registration process is available within Programs > Participant Reg > Setup.
There are two options:
Allow Multiple Seasonal Registrations for the same Participant: Prevent the same player from registering for that season more than one time.
Allow Multiple Grouping Selections for the same Participant: Present the available groupings as checkboxes (instead of a dropdown) to allow registrants to check multiple groupings during a single registration process - this would be an ideal setup option for camps and training programs.
