You can put a "hold" on all of your mail but it has to be for a minimum of 3 days. You can go online and do it but make sure you put that you would like to pick up your mail not that you want your carrier to resume it.
This is forum allows other Google users to share their knowledge for general questions. You probably need to contact the post office directly regarding making arrangements for a specific package. Google "USPS Tracking" if you have a tracking number and want to see the status of your package. You might be able to call the post office but as busy as they are this time of year you might be better off going out there in person if you need to make other arrangements for your package
