Hey Kim,
It sounds like you want to create a nurture track, or the newly created Engagement Program. Are the emails you send every week the same? Regardless, you can add new content as you go to the Engagement Program and build it out as one campaign. It all depends on what you are looking to do.
I admittedly do not know too much about it, but I would take a look at this
Deep Dive for Engagements and see how it will apply for your needs.
