Create Sliced Invoice Quote user from WP Booking System

I think Sliced Invoices and WP Booking system are both superb. However, as with any form of software, users will always have requests and here is mine.

Alongside WP Booking, I use Sliced invoices. Both work great, but don’t interact with each other, I would like to auto create a user entry in Sliced Invoices Quote client when a booking is made through WP Booking. This would save me from having to retype all the details from WP Booking into the Quote user of Sliced Invoices. Possibly via some sort of ‘Add to Users’ button. That would copy all the details across to the User in Sliced invoices Quote User.

It’s quite possible that it’s already there, but I’m missing it.
