Yes there is: So you don't have to fiddle with it ever again.
Ah, you might say, that defeats the purpose by allowing outside air to influence the inside temperature!
Not at my house, or at least not so much.
A couple of years ago I scored a fireplace screen from Craigslist for $45. It consists of a frame clamped to the fireplace itself, two wire-mesh doors, and two tempered glass doors. After enjoying the fire as much as needed, I can close all the doors and make the front of the fireplace almost air tight. No air, or not much, can enter or leave the fireplace. And I don't have to fuss with the damper at all. Plus, I don't have to reach into the still smoldering embers to engage the hot damper.
And before anyone haruumps "There's still SOME leakage!", I'll admit to that, but probably no more so than around a closed damper.
Mine is similar to this one: http://www.homedepot.com/h_d1/N-5yc1v/R-202325785/h_d2/ProductDisplay?catalogId053&langId=-1&keyword=fireplace+doors&storeId051#.UNsAH-THWzk
