Intergrating local pick up with shopify and shopify POS

We have a website for ecommerce sales as well as a brick and mortar store that uses shopify POS. With multi location fulfillment we were having issues with inventory as Shopify pulls from the other location if one location is out of stock. We didn’t want this so I turned off the brick and mortars ability to fulfill online orders but now that has seemed to take away the option for local pick up. Is there a way to offer local pickup when someone checks out online even if that location is not set to fulfill online orders?
