Possible to Have Bootcamp Like Functionality Shortcut with Clover?

I'd be extremely grateful if someone had an answer to this.

On a mac, using bootcamp, the mac will boot into a default volume depending on what you set up as your primary boot partition in your system preferences. At any time during the boot, you can hold the option key to select a boot volume, otherwise it'll boot into the default volume you set.

My question, in order to speed up bootup, is it possible to bring this functionality over to Clover? I'd love to be able to have it boot straight into OSX, unless I want to do some gaming, then I could hold the option key to get into the other partition.

Thanks for any help on this first world problem.
