Woocommerce product variations linking

Hello all. I have a woocommerce site and using bdroppy dropshipping plugin to upload and actualize my products. The issue is that all product variarions are with sizing. If a product is available in different colora. It is uploaded as another seperate variation product. They have the same product title. How can I automate that all products with the same title are merged together as 1 product variation. As well as for new uploaded products to get recognised.
