I have the following question with regards to Pastel Partner. I would like to know if the below scenario can be created using Pastel Partner / Pastel Partner Express?

Supplier G - create purchase order for goods
Goods are delivered. Create supplier invoice.
I want to add the following additional costs to my invoice

Does not make sense to create purchase orders for the following costs because no grv is required. The costs are not tangible.
Supplier S – Shipping costs
Supplier C – Supplier invoice created for local courier services (delivery of goods)
I want to link them all to create one supplier invoice.

Is it possible and how would I get this done?
