Allow us to add PDF documents to individual products in our products lists!

It would be incredibly helpful if we could add/attach PDF documents to individual products listed in our products lists! We want to be able to attach documents such as installation instructions, detailed spec sheets, other associated vendor invoices, etc. related to the various products. Currently there is no elegant or good way to send/share these other than in a separate email that can get lost and is hard to keep track of. It would be great if we could control if the attachment was visible or not visible to our clients and when they would get notifications on them. Getting a notification each time an attachment is added to a project is cumbersome and can get annoying to clients, especially if they don’t need to see the attachment right away or at all. Really hoping you can make this helpful update soon!
