The Open New Hardware Target wizard is also what populates a list of previously connected hardware targets. Instead of connecting to a hardware target by going through the wizard, you can re-open a connection to a previously connected hardware target by selecting the Open recent target link in the Hardware Manager window and selecting one of the recently connected hardware server/target combinations in the list. You can also access this list of recently used targets through the Open Target selection under Hardware Manager in the Program and Debug section of the Vivado flow navigator.
