Merge product for sigle product multi vendor

Good morning, everybody, I’m new and I moved from dokan to the wcfm.

I wanted to ask two technical/functional things.

1) Can i merge 2 equal products (same sku) but loaded at 2 different times by 2 sellers, to make it 1 product with more sellers? (they didn’t notice the product already present and didn’t use the clone function)

2) if a csv is loaded by a seller, is it possible that by means of sku example, it is possible to automatically merge the products ? i.e.. I already have online the product with sku: “example-123” and a seller loads his csv with a product with the sku “example-123” in the list, can it merge automatically using the function one product and several sellers ?

Thanks in advance for your answers
