Product Codes for physical products

Hello all. So basically I own a lot of DnD supplements for 5e(most of them) because we used to play in person but we've just switched to Roll20. Is there any way I can get these products on my account without rebuying them? I have them all physically right next to me, so I can still use them, but it'd be helpful if they were all on my R20 account. is this possible? Thanks. 

The Aaron said once: Short answer: No Digital content is a separate product.  What you are paying for is many, many hours of developers assembling the various pages, handouts, characters, dynamic lighting (if you have a Pro or Plus subscription), etc.  It's comparable to having the book a movie is based on: the content is mostly the same, but the format and presentation is different.   Audio books and physical books might be an even better comparison.
