Wordpress multiship address plugin customization to a b2b multivendor site.

Hello, I am an operation of just 3 people so please have mercy in your proposal. Thank you ahead of time for your consideration on this project. This one piece of customization is what holding me up from getting this project off the ground. If you can truly help me with this project I would seriously consider asking you to be a part of the project. I have Woocommerce Shipping Multiple Addresses plugin, I need help to customize and integrate the plugin with Wordpress, Woocommerce and also the WCFM Multivendor which make up as the core pieces that comprise my website. Wordpress Mulitple shipping address is a plugin that allows the registered buyer to have multiple shipping addresses in their account. This is so when a purchase is made via the shopping cart a customer may choose which address that product may go to. The Shipping Multiple Addresses plugin has other features such a splitting up the cart items by quantity to their respective multiple address locations that they need to go to. An example of this would be the buyer has multiple physical stores which he needs to stock his purchased products. The buyer has created an account that gives him the ability to list all of his stores with their respective addresses. When the buyer has chosen the products he wishes to purchase the shopping cart then will allow choosing which address that product will go to. There is more detail to this but that's the general explanation. Also, an invoice is produced for the buyer listing the purchase they have made listing each store and what each store is receiving. The same is produced for the vendor(s) in the WCFM multivendor side. Essentially that is what Shipping Multiple Addresses plugin does. this a link that shows what the plugin is supposed to do.

The pdf invoices produced for the vendors in the WCFM Multi stores are not showing all of the order. Just partial list. 3. When the buyer has to select what products are to be sent to the multi-shipping addresses if it's just a few products it is easy, but when a very large order is done then it is extremely difficult and confusing.
