Our company has hundreds of thousands of variants, because we custom build products and each product can have numerous options.
Instead of importing possibly millions of SKU Variants, I wanted to look into building the Variant SKU based on the options in real-time (our current site does this by appending the Option SKU Name).
What classes would I need to override to go from pulling existing/matching a SKU Variant when a configuration is built, to appending the SKU Options to build the SKU in real-time?
