How to link an existing supplier to an existing customer?

Summary:

is it possible to link a supplier and a customer that are already created.

I saw some articles that shows steps to link customer to supplier while creating a new supplier via FBDI import supplier by giving customer's name and registry id so the that the new supplier will be linked to existing customer.

But I wanted to link a supplier and customer where both are already created in Fusion.

Thanks,

Sneha
