Thanks Josh, I just created a little site with my template and added that to the product information. I also tweaked the code of my template a bit and wanted to re-upload it, but I couldn't find a way to do so, so I went ahead and just created a new product page with the updated file. Would it be possible to add a feature where sellers can push out updates for their digital goods on their product page?
For those interested, you can check out the template in action
here.
Now that I think about it, yes, I can allow you to change the file for updates. I am currently adding functionality that allows you to email the Edit and Order form links to yourself. As soon as I am done with that, I will add the ability to change the file attached to the product.
