Make Campaign CPT readable and add taxonomy options

Hey guys, it’s a bit unfortunate that there is currently no way to build a custom archive of newsletters, as the Campaign CPT cannot be read by any other plugin. It would be great if this could be changed and a taxonomy would be added to the campaign CPT so that either one could have a category field or a tag field, which would then allow to filter newsletters based on category or tag! Would be great if this could be added! Kind regards, Philip
