Efs, hosts, aliases an ports.

Hello all.

I was wondering if it was possible to set up 'aliases' for hosts with weird
ports in my .netrc? 
for example, rather than have to type in:

/user-NY6FVG9Wdl21TRBrS9/[email protected]#portnum:~/myfile.txt

i could have my .netrc pick up the slack and use:
/machinealias:~/myfile.txt


regards,

Tim.
