Hi,
you are dead right.
But, since for our site all services will be performed by the same entity so for;

Polvcom Branded Services
Installation Services
Premier Services
Partner Branded Services
Transition Ensure Services

I think the Product_Description will be suffice to identify them.
In practice I can use CRON to automatically UL the new .csv monthly but with a start by date created in the HikaShop ECommerce module, so I will need to go through the Uploaded .csv to manually edit Categories and Products before the publish date is reached.
I cant see any way around this since as you so rightly pointed out, the original Excel sheet provides no way to fully parse.
