I believe that when you say "open the program", you mean the DirectSOFT Project file, and that it will go online automatically also.
Yes, that feature has always been there whenever you save an Online project to disk. The project has the link connection stored as part of its file.
Opening a disk project that has a configured comm link on a new PC will also re-create the link on your new computer if that comm link is not actually set up yet. The project file also stores some of the link parameters in case the link with that name is not currently defined on the PC (think projects stored on floppy disk, moving from maintenance laptop to laptop).
