Will it ever be possible for Website X5 developers to create the ability for us to upload multiple files for one Item Card so that a customer has the option to buy different types?

What I mean is this:

Let's say I run an Online Store of digital products and I sell images.  I would like to be able to upload the following on the backend: 

1 JPG file in 8.5x11 size. 
1 JPG file in 12x14 size. 
1 JPG file in 16x20 size.
1 JPG file in 28x36 size.

This way, when the customer buys an image on my store, they can choose which of the options they'd like to buy.  And depending on their selection, after purchase, they would receive an email with the correct download link for the option they chose.  As it stands, they can only receive one download link altogether, so this is not very user friendly at this time.  And we as creators wouldn't want to create multiple shops for different sizes when it would be easier to create one shop that allows our customers to choose the option they want to buy.

Or this is another scenario:

Let's say I run an Online store of digital products and I sell eBooks.  I would like to be able to upload the following on the backend:

Basic version of my eBook (24 pages)
Premium version of my eBook (56 pages)
Master version of my eBook (124 pages)

As you can see, I would have 3 different options that I would offer my customer.  Again, depending on their selection, they would buy the item they want and then receive a download for THAT item, versus all or only one option.

Or Let's say I run an Online store of audio products that I sell.  My customer has the following options they can choose from:

MP3 Low Quality version
MP3 High Quality version
WAV  Audio  Format
WAV  Audio  High  Quality  Format

As you can see, they have options again.

My hope is that your company plans to look into this as to how a future feature will allow us to be able to upload various files for the same product, in different options, so that the customer will receive only the option they are wanting after purchase.

As it stands right now, we can only upload one file for each product, and would have to make multiple Item Cards for each option.  So if I had a store of 30 products, each with 3 options, instead of making 30 Item Cards and uploading the options for each, I would literally have to make 90 Item Cards to compensate the options a customer would have.  AND, it would not look well structured on the Catalog shopping page.

I hope that something like this is possible for the near future as it would benefit all kinds of people who build with your websites.

Thanks in advance.
