Blog Pagination in Editor

Hey guys,

I was wondering if it is possible to change the amount of posts shown on a Blog page via the Editor?

Because let’s say if a client wanted to have 6 posts shown on the page, but then in some time he changed his mind and wants 12. Does it mean that he would need to ask me to change it via the Designer or is there a way for him to change it himself? Also is there a way for him to change the posts order himself with the help of Editor?

Thank you
