It won't expedite anything if that's what you're asking. You can Google how to link pr card application, there's no need to submit an application, there will be one in the system for you to link, just Google it.
As for getting PRTD, really use your judgment. Can your schedule tolerate a potentially long delay? Some people aren't that established in Canada and can go abroad for a long time, others, are actually working here and have family who is also working and studying. If you are from the second group, you can't take an unpredictable long delay in coming back, as that translates into a potential loss of your job and kids missing daycare/school etc.
