Ah, thanks for writing back with a solution. So often I see "help me" and then "nevermind, I got it", and of course that doesn't help out future searchers

Just to add this this, could can also add your specific helpers into application/helpers/ if you wanted to, may make upgrading easier, depending on how you do it, but there is no technical advantages to this if you have only 1 app running off CI.
