Identify Products

[Kend]

How do I add the "Item ID" to products?

When there are three items for $9.95, I need some way to identify which one I'm looking at (after downloading a month's worth of purchases). It would help to have an "Item ID" assigned to each.

Currently, on the downloaded spreadsheet of account activity, the "Item ID" column contains the word cart.

Is this as simple as adding this to the code?

<input type="hidden" name="item id" value="product 1">

Thanks,
