Add a variable to identify the OTA or booking source in reservation notifications

It would be very helpful to have a variable that identifies the booking source or OTA in reservation notifications and automated messages.

Currently, when a new reservation notification is received, it does not clearly indicate whether the reservation was made through Airbnb, Booking.com, VRBO, Direct Booking, or another channel.

Adding a variable such as {{booking_source}} or {{booking_platform}} would allow users to include this information in automated notifications and templates.

This would make it easier for property managers to quickly identify the origin of each reservation without having to open the booking details.

Example use case:

"New reservation for {{listing_name}} made via {{booking_platform}}."

Possible values could include:

• Airbnb

• Booking.com

• VRBO

• Direct Booking

• Other connected channels

This feature would improve notification clarity, automation workflows, and operational efficiency, especially for users managing multiple channels.
