ASA Config - Open port 3389 for all IPs

[RMurr34]

Hello,

I have an ASA5510. Whenever I setup a new Windows VM I add the IP to the access-list and allow access to port 3389. I also create a new static map. I'm going to build out a new
ASA and I'm wondering if I have to add each IP to the access-list or if there's a way to just open port 3389 for all servers so i don't have to keep adding them every time I add
a new VM. Here's what I have:

access-list 102 extended permit tcp any host 109.xxx.xxx.157 eq 3389
access-list 102 extended permit tcp any host 109.xxx.xxx.158 eq 3389
access-list 102 extended permit tcp any host 109.xxx.xxx.159 eq 3389
access-list 102 extended permit tcp any host 109.xxx.xxx.160 eq 3389
access-list 102 extended permit tcp any host 109.xxx.xxx.161 eq 3389
access-list 102 extended permit tcp any host 109.xxx.xxx.162 eq 3389
and so on...

Any suggestions?

Thanks!
