...which change the way of booking and offer new opportunities.  

- all customers are registered users in wordpress (Amelia customer role)
- every customer can select (predefined) services
- services (Amelia employee role) are predefined for period and max. number of participants
- each customer must select other customer(s) in addition to themselves (they are always part of the booking)

Ideally, customers can then be divided into different groups, which offers additional options. (Restrictions: age classification, affiliation, number of max. bookings, etc.)

At the moment, we're using a very similiar booking plugin, which is lacking the same functionality. There, we have to create all customers in custom fields. However, this is cumbersome (customers have to be listed several times for different services) and prone to errors, since there isn't any logic available in custom fields. E.g. a customer can be selected multiple times in different fields.

A frontend solution might be easier to implement, because it seems already available (basically) in the backend, instead of adding additional logic into custom fields.

Would be great to hear, that this might be worth to be considered in your plugin.

Kind regards
