Add attachments from Articles

Hello,

We often use Articles to send standard replies to tickets, but some stuff requires that various documents be attached - a couple of .pdfs.

I just tried it to set up a File Custom Field, but it just puts at the end of the text:

File:
----
original_filename_here.pdf

Would seem that this feature is nearly there, and someone even wrote and submitted a patch for it in 2017: https://rt.bestpractical.com/Ticket/Display.html?id=32708

And it’s also requested a few times here:

This would be a great feature to add for RT5 as it would make articles more useful.
