Limit The Amount Of Products From A Single Supplier?

Hi all,

I was wondering if anyone knows how to achieve the following?

My store has 2 suppliers set up.

Supplier 1 - The customer can order any number of different products from this supplier.

Supplier 2 - The customer can order a maximum of any 2 products this supplier.

I am not sure how to achieve this. I tried to see if I could limit via shipping method. So more than 2 products from Supplier 2 would not provide a shipping option but this does not seem possible?

Any help would be appreciated.

Thank you!

I am afraid, the Suppliers functionality does not have such limits
