Can I associate my email templates with a campaign to prevent screw-ups?

I am running 2 nearly identical campaigns at the same time, and I'm using email templates that are nearly identical for each campaign. (One campaign is focused on bigger businesses while the other is focused on smaller businesses.) Pricing is different for each campaign, so it's critical that I don't accidentally send out the wrong email template to a lead. Right now, I can see all my template choices whenever I send out an email, so I could easily click the wrong one. Is there any way to associate my email templates with a campaign (or any other unique identifier) so that when I'm sending out emails, only the template choices for that campaign will be visible?
