Wordpress Mulit-Vendor Product Upload

Working on a project that will somewhat replicate SmugMug but specific to motorsports. The software I found that almost works is called Dokan. It allows for all the multi-vendor features we need to make this site work with the exception of just one. The one issue this software has is that it only allows vendors to upload 1 photo (product) at a time. Motorsport photographers can take hundreds of photos each night … and only allowing them to upload one product at a time would be very time consuming for them. So, we need a plugin built to work with Dokan that will allow the vendor to bulk import photos (product) into this software (not by CSV, XML, etc..) but rather through the upload interface. In doing so each photo would take on a specific pricing template that the vendor can set-up on their own (Example: Digital Download $10, 3x5 Print $8.00, 8x10 Print $15.00, Posters $25.00, etc..). Does that make sense? You can see how their software works as a vendor from the below demo link. Once logged into their demo click Products > Add New Product [login to view URL]
