Paperless-ngx – Open source document management system
I started using paperless a few weeks ago and thus far i really like it. However i have a cuse case, of which i am not sure if there is a way to solve it using paperless. 
That is having something akin to an ongoing chat/thread that you have with a corespondent.If I want something done by a third party i.e. my bank ill send them a mail or setup a meeting with a representative. This creates documents, that i want to add to paperless. Over the course of the next weeks additional documents will be created that outline the "progress" of the topic. I want all of the documents for this single issue im trying to solve to be kinda linked together, so that i always know the current progress and where it all started.Does anyone here found a good way to solve this issue or is there even a built in function from paperless that i did not see ?
