XF 2.2 Article tags in RSS feed for hashtags

[optrex]

I'm using an RSS app that scan my feed and web pages for topic / category tags and automatically include them as hashtags in your posts into twitter.
They look in your RSS feed items for ‘category tags’ and scan your pages for <article:tags>.
Currently that criteria picks up the name of my forum (category) title.

category domain="https://url"><![CDATA[forum Title]]>

is it possible to add into the feed <article:tags> so that it actually picks up the tags associated with a thread?

Any ideas how I could add tags into the feed please?

It would require custom development.
