Update only one category

[Walter Alfonso Ruiz Canal]

I would like you to modify the update series so that only one category or all series can be updated as is done now.

I have many series in bookmarks and I divide them into categories to see the genre that I want to see at the moment.

When I want to see if new chapters came out I have to update all the bookmarks. But I don't want to update all the bookmarks since it takes a long time. I just want to update one category.
