Mark individual category as read from community

Hello, on the Category tab of the Tabs widget there is a Mark all forums read link at the bottom which has a URL with the path below.

/member/markAllForumsAsRead

It appears from this post that there used to be a similar link at the bottom of the category page that was scoped to that individual category. This was apparently at a time when there was pagination instead of show more and the link is now gone.

So, two questions, is there a way to restore this link. I have looked through existing widgets but couldn’t find it included anywhere.

Failing that the /member/markAllForumsAsRead link appears to be an actual link that eventually lands you on the home page. Is there an individual category version of this URL we can use to recreate it with a customization. For example, something like /member/markCategoryRead-[category id]

Thanks
