I want to change the location of COM_MATUKIO_YOUR_BOOKING_IS_ACTIVE_AND_RESERVED in the email generated when a booking is active and reserved but can not find any reference to it in any of the email templates.

Customers are getting an email like this

Your booking is active and your place(s) are reserved.
Dear Dr xxx yyy,

Thank you for your booking.
<snip>

I think it reads better as

Dear Dr xxx yyy,
Your booking is active and your place(s) are reserved.
Thank you for your booking.

I can find no way to do this.
