Post Secondary Question: Updating Schools on 'Small/Irrelevant' Job.

Do you expect any more significant updates previous to the end of the cycle? If not, you could make this what I'd essentially call a combined letter of update and interest, where you let them know of the additional activity(ies) you're doing and then go on to why you think X school is good for you, with specifics. Extra points if you can make that tie into your update and make it sound like a logical progression.

If you are expecting more significant updates, I would wait for those given this one is benign.
