Thanks for submitting your feature request @queenrose, and welcome to the Community!
I can see why some businesses may wish to make exceptions to their delivery parameters for some customers, clients or specific addresses. Indeed, there may also be a use-case for limiting order acceptance to only certain addresses.
At this time, there are no plans in the pipeline to amend the current delivery policy options available to Sellers. However, our product developers do review Square Online feature requests regularly. So, it is possible that a feature like this could be implemented if more Sellers express their support, and provide specific use-cases for the team to consider.
