We have a department with several O365 Groups. They also have a Site Collection (non-group-connected) in which each of the O365 Groups is listed as a member. So, all of the members in each Group can access the Site Collection. Great.
Now, they have a "Telephone Directory" list (a custom list) in the Site Collection that they'd like to render (in a "List Web Part") on each of the Groups' SharePoint sites. Obviously, there could just be a static link to the list, but that's not the same thing. With SPD 2010, you could create a web part that would reference the source list for data and deploy that WP to other sites/site collections, but that doesn't appear to be possible in SPD 2013. Also, I know that the "Relevant Content" web part can be used to pull content of specific types from across the tenant, but that wouldn't really work here. The Content Type is "Item" and that web part can apparently pull from the current site collection or all site collections (not one specific site collection).
Anyone know if what they want is possible without going overboard? I'd also considered creating a simple PowerApp from the list and embedding that on the Group Sites, but since PAs can't be shared with O365 Groups, just maintaining the permissions would be a royal pain.
