Yes, both is possible. For NATing only one port, specify the port-number in the NAT-command. Here is an example for RDP:
object network TERMINAL-SERVER
host 10.10.10.10
nat (inside,outside) static 192.0.2.1 service tcp 3389 3389
For NATing every service, just configure NAT for the IP address:
object network SERVER
host 10.10.10.11
nat (inside,outside) static 192.0.2.2
