Display name and/or path of currently viewed email in mutt/neomutt

I'm using [neomutt](https://neomutt.org) (an updated fork of [mutt](http://www.mutt.org)) as my CLI MUA (read: mail reading software in the terminal) and have all my messages synced offline using [isync/mbsync](https://isync.sourceforge.io/) and stored in the maildir-format on my Debian Stable system. Sometimes I want to reply to a message and attach another email (e.g. as a reference). This can be easily done when using the maildir-storage format since all messages are separate files; I just need to attach the file in my local folder. The problem is that I have difficulties finding the email files. Obviously I can search through all of my messages (e.g. by using [mu](https://www.djcbsoftware.nl/code/mu/) , which is my mail indexer) and then attach it, but this is tedious. It would be a lot easier to just display the path and filename somewhere when I read an email, optimally in my pager within neomutt. But despite looking for a solution, I wasn't able to find that. Any ideas or workarounds?
