Ability to set different message for individual and group bookings

What is the best way to create a different set of messages for individual and group bookings? For example, for the thank you message after successful registration, there is only one setting in the backend for both individual and group bookings. I would like to customize the way the message looks and do not wish to use the [REGISTRATION_DETAIL] tag, but instead use specific tags for each field. In my case, I can not just add all the tags since some fields are only used for individual booking, while others are only for group booking.

The only way I see this can be fixed is either:
1. Use conditional statements to hide/show fields (hide/show if individual or group, hide if empty, etc)
2. Use a separate template for individual messages and group messages

Hello

We don't have separate messages for individual and group registration, there is only one message

So if you need two separate messages, each message for a registration type, you will need to customize the extension to support it
