NAT issue

I have an application that requires that the host clients retain their source port. The source ports range from TCP/10000-10040 and the destination server listens on TCP/12000. I need to NAT these hosts to a single IP address as well. Can I use a Dynamic policy NAT Rule for each port to retain the source port during NAT(PAT)? This is on an PIX/ASA.

If I define a DynNAT Policy for each source port starting with 10000 will it then use port 10000 when it NATs? This is my best thought process as the clients are DHCP hosts and it would difficult to manage them with static IPs and Static NAT entries.
