Can I change "followup by e-mail" link to a checkbox?

Right now, whenever I answer a question I can click “Click here to be notified of followup answers via e-mail” so that I know when there are new posts. However, the option is a link. So, if I just finished typing my response and click the link, I lose what I typed when the screen refreshes. So, I have to type my response, submit it, and then click the link after the screen refreshes. It would be nice if the follow up via e-mail option was a checkbox instead, so that I could write the answer, and check the box at the same time instead of having to perform two steps. You can see an example right here in the WPMUDev forums. Is that possible in the Q&A?

Thank you,
