I need to make it easy for Wordpress blog posts to be assigned to specific locations of a business so they can be grouped into their own collections for display on blog article archive landing pages for each location. Some articles my be relevant to multiple locations as well.
I cannot use categories for this. Ideally I want something similar to categories, but we're already using 70 other categories on this site for actual post categories. Category blog post archive landing pages will have a wildly different look and feel than the location based landing pages, so categories will not work for this.
I need an alternate approach flexible enough to where it's as easy to assign posts to locations as it is to click a check box for assigning categories to a post, and robust enough that I can indeed create those location-based landing pages that can filter out entries from all other locations.
I'll also need to filter posts by category within a location's entries, if possible.
How can I pull this off successfully?
