Multiple Countdown Timers, simultaneously displayed

Hi, one of the pages on my site will have multiple auction items, each requiring a different end time. Hence, I need to set up multiple countdown timers and currently it seems that I am only able to set up one countdown timer, since the short code is generic and not specific?

Is there a way to assign a specific short code to a created template? What I mean by that is, I create 1 timer that expires in 4 days, another one in 6 days etc. I save each as separate templates (e.g. Timer4day), and a associated short code is created, like [timer4day-countdown], which can then be placed next to the item which auction ends in 4 days.

Thank you for your input and reply.
