I have a brand new install of WordPress and manage a baseball blog. I have many categories of certain players and want to put them under a parent category of their current team. For example, the category 'David Ortiz' should be under 'Boston Red Sox'. Easy enough... unless you have over 1,000 categories (and counting) like I do. I moved over from Movable Type and the parent/child connection did not take when I imported archives.
It seems like there's no way to check off a certain number of categories and then mass-edit them to all have the same parent. I've been searching for a plugin and am surprised not to have come up with any. I remember a very old version of WordPress having this feature, so I'm quite surprised it's gone now.
Can anyone help, or am I stuck going category by category?
