Hello there @cs,
Thank you for posting about this in the community. We are thrilled to have you with us
At this time, UPS Daily Pickup is not available via UPS thru ShipStation. This is actually an Idea post that one of our other users put up! You can vote on UPS From ShipStation Daily Pickup here!
Additionally, you can of course set that up with your UPS account directly in the meantime.
