Easy Populate Oscommerce Custom

Our clothing store is powered by oscommerce cre loaded. All of our items have many product attributes. We need easy populate to generate item name, item number, price, and three or four specific product attributes that are most important for product updating monthly. Example 1: We sell dresses, shirts, pants, purses all from one manufacturer that come in the colors Purple, Black, Red, White, Blue, Green. If our manufacturer discontinues Red, and Blue, we need to generate easy populate tab deliminated so we can delete Red, and Blue from the excel file for all of these items and re-upload so changes can take effect in database. Example 2: We sell 100 different shoes from one manufacturer. They come in size 5,6,7,8,9,10,11,12. If manufacturer no longer makes size 5, we need to edit and delete size 5 in easy populate for 100 different shoes, upload so changes can take effect in the database.
