Prepopulated webform

Hello,

I created a webform and would like to use it for several different items on my web page.  One field in particular I would like to prepopulate with that items respective data.  I know I could create several webforms, each with the data for each item filled in, but this seems tedious.  Can I use the one webform and somehow have the data prepopulate based on that specific link I create?  Or will I have to create a sepearate webform for each item to have the unique data entered?
