Feature Request: Allow Editing the “Message” Field for Individual Invitees

Hi Fluent Booking team! 👋

First of all, thank you for the great work on Fluent Booking.

I would like to suggest a small feature that I believe would significantly improve the booking management experience.

Currently, after adding an invitee to a booking, the "Message" field becomes read-only. It would be extremely helpful if this field could be edited afterwards (for example, via a small pencil/edit icon, just like the email field).

This would allow users to:

• Personalize the message for each invitee after creating the booking (eg.: change the priority for the meeting).
• Correct mistakes or update the message without having to remove and re-add the invitee.
• Save time when managing bookings with multiple participants.
• Reuse the same booking while sending different contextual messages to each attendee.

Since the email field is already editable, having the same behavior for the Message field would feel consistent with the rest of the interface.

I think this would be a small UX improvement with a big impact on day-to-day usability.

Thanks for considering it! 🚀
