I understand how this should work, unfortunately I don't get it to work. As assortment-task doesn't have any defaults I have to pass in comparator, sortby and filterer as well. Might be that I'm doing something wrong here. I tried writing my own task, but I'm stuck as boot.core/tmp-dir! creates an odd path: /home/phil/.boot/cache/tmp/home/phil/src/ok/site/fe7/f4i83m. I'll prepare a PR to show some code.
