List all TAGS for all posts under a collection

Developer help

I have a collection for all FAQs (filtered using the faq tag) on my site accessible via /faq/[some-faq]/
I have assigned a minimum of two tags to the FAQ posts for example faq,tax or faq,exemption.

I would like to list all tags for the posts under this collection i.e exemption, tax etc. In other words, a list of tags for every post that has faq as primary tag. Is this something possible in Ghost?

Here is my routes;

collections:
  /faq/:
    permalink: /faq/{slug}/
    filter: 'primary_tag:faq'
    data: tag.faq
    template: faq
