EasyRoutes doesn't have a setting that hard-locks a stop to one named person, but you can require and document the hand-off. Add a required Driver Task — a text field for the recipient's name, or a checkbox confirming "handed to named recipient" — that must be completed to mark the stop delivered, and note the required recipient in a stop note so the driver knows who to look for.
Pair it with a required e-signature so the signer is captured too. Works in both EasyRoutes for Shopify and EasyRoutes for Web.
