How Can I Get My Mac to Automatically Connect to a Bluetooth Speaker on Startup?

The subject pretty much says it all. I have a Samsung Radiant 360 Bluetooth Speaker that I'm using with my Mac . The speaker connects via bluetooth just fine. The problem is that I have to manually reconnect to the speaker every time I power on/restart my Mac by tapping on the Bluetooth icon on my menu bar, selecting the speaker from the list, and then selecting connect.

Is there any way to set my Mac so that it automatically makes that connection on start up?
