Sure! You can breed one male with many females.
Stop feeding the male and the females in November, and keep their temps up for two weeks to allow them to digest the remaining food in their digestive tracts. After those two weeks, cool the snakes to about 55°F for 2-3 months. Make sure they have fresh clean water during this time, and take a look at them every week or two to make sure they are not developing a respiratory infection. After the two or three months of brumation warm them back up to normal temps over a week. When they are warmed back up, feed them like crazy, esp the females. After the females shed the first time out of hibernation, put the male in her cage, and they will breed. You can then put the male back in his own cage after the breed. Some people like to re-introduce the male to the female for a day or two a week or so later to make sure it was a success.
Keep and eye on the female... continue to feed her more than usual, and she will eventually refuse food. Shortly after that she will shed. Put a egg box in her cage after this shed. And about a week after that she will lay eggs.
Remove the eggs and place them half buried in a mixter of 50% (by weight) water and 50% (by weight) perlite. Be careful not to turn them. I like to put a small dot with a sharpee marker on the tops.
Incubate them at 82°F.
And chances are they will hatch...
