Hello Sandra,
Thanks for using our plugins an for your great question.
What you describe is not possible that way out of the box. It would likely be achievable with some custom development to get the functionality you described.
Customization, custom development is beyond the scope of our support but I can share with you this list of freelance developers who could help you out with a development project like that. They are known names in the community and are not affiliated with us.
The other option could be using our Event Tickets and Event Tickets Plus plugins (and an eCommerce plugin like WooCommerce or Easy Digital Downloads) to sell tickets to your events. Since a payment gateway to PayPal exists in both you could use these easily.
I hope this helps. Let me know if you have any further questions.
Cheers,
Andras
