[exim] per user accepting , but has wildcards etc

Hi list

I have a route as so

account_bookings:
debug_print = "R: real_local for $local_part@$domain"
driver = accept
domains = +local_domains
local_parts = bookings
local_part_prefix = *-
check_local_user
transport = LOCAL_DELIVERY

This basically routes mail for

*-bookings@???

Ive been trying to figure out how I can have accept (or do I need
multiples routers for this) for an email address like:

123456-username-bookings@??? to goto
username

If anyone would so kind as to share some tips or advice as to how I can
achieve this, I would be most greatfull.

Kind Regards, and thanks in advance
