Can ag search sub-directories with the same name, within a bunch of directories?

Given a directory structure such as: dev/project1/assets/** dev/project2/assets/** dev/project3/assets/** Is it possible to search, from within the dev directory all assets directories only. Given that the project directories will include other sub-directories. I don't want to have to explicitly name each project directory. But something like search on /*/*/assets. So x directories deep, with a given name.
