Different prices for multiple atendees

Hello! I have a question:

https://wpeventgenius.com/docs/allowing-attendees-to-register-multiples-guests-for-events/

We are looking at this possible situation:
An event that offers 2 ticket TYPES:

1. members (free)
2. non-members (10€)

However, we’d like to add an option for the MEMBERS:, if they bring guests, each guest would be 5€ (for example).

Is this possible?

(I do realize that the PRO version is necessary for allowing for multiple guests, and for different ticket Types).
