Hi David,
On 8.2 it is not supported but on version 8.4 it is. What you will need to do is a NAT statement. The downside is that you miss used granularity compared with 9.X
object network scansafe-protected-network
subnet 0.0.0.0 0.0.0.0
!
object network scansafe-proxy
host
!
object service original-http
service tcp destination eq www
!
object service proxy-8080
service tcp destination eq 8080
!
nat (INSIDE,OUTSIDE) source dynamic scansafe-protected-network interface destination static scansafe-protected-network scansafe-proxy service original-http proxy-8080
