Loopbooks in MAC

Ran into an issue today attempting to configure GNS3 for a routing lab. I was looking for a way to add another loopback interface on the mac. I did not find an answer. I attempted using ifconfig, but I get this error:

sudo ifconfig lo1 create
ifconfig: SIOCIFCREATE2: Invalid argument

Strange, the GUI does not support creating real interfaces, only virtual ones which is not good in binding with GNS3 because the appliciation wont detect it :-/ still stuck.
