Hello all you Zen Maniacs!

I'm looking for a mod. that will allow me to date/time stamp any certain product listed in my Zen-Store. In other words I'd like to be able to control when a product is listed for sale and when it ends. For example; an RCA 37" TV was on sale from 12/01/2006 until 12/02/2006.

Is this possible? Please help me if you're able.

Thanks in advance!
