Replicating pages

There are a few places on the website that I’m trying to manage that need to be replicated, e.g. https://potomacfiberartsguild.org/meetings-workshop-schedule/ and https://potomacfiberartsguild.org/calendar/2017-18-workshop-registration/ I’m not managing the commerce elements of the site, just the easier stuff, but I’ve been told that they are replicated because members may just go to the ‘Members Only’ tab and not to the ‘Programs + Workshops’ tab. The people that I’m replacing are saying there is no way to duplicate the pages that are appearing in two places, that every change has to be done twice. Is that true? It seems laborious but, frankly, if that’s what is needed to make people see the workshops we are trying to fill, it’s worth it. I’d just like it to be a little less time-consuming on my end, if that’s doable.
