Pluginhive Previous Booking Mass Deletion

Description

Hi Everyone,
We have a client who is looking to delete more than 20 bookings at a time, which this plugin allows https://www.pluginhive.com/product/woocommerce-booking-and-appointments/in the Admin - Bookings - All Bookings section, we can only delete 20 at a time. We need to increase this to 400/500 at least. We have spoken with plugin hive, and they advised that the bookings sit over several database fields, so the best way to delete them is via this section they built.
We will require this to be tested on a subdomain we have for the client first, then rolled out, if successful to the main website.
Please note this can not be done by emptying one database table, as the details site along several.
