I am currently building a site that will go out in issues (issue 11, issue 12 etc) and would like my permalinks to reflect this. However I do not know how to go about it. Currently, the permalinks use the %category%/%postname%/ layout but I would like them to look like http://example.com/issue/11/category/sub-category/postname. To save time, I understand that default is for wordpress to grab the category with the lowest ID and use that as the base.
Thanks in advance
