With seasonal ITS rules being a thing now it'd be great if they could make their way into Army in one way of another. The least time-consuming way to go about it would be to include a table at the end of printed army list (with the usual on/off toggle in options) listing season-specific rules (like Ironclad, Bravery, Landing Assistance, Long Service, additional orders for Datatrackers when applicable, etc. Basically everything that modifies printed unit skills or stats, and can be forgotten when not printed out. Because such things will be forgotten. If a unit gets an additional skill for the duration of the season it'd be best to include it in profile. Though I understand it could be a time-consuming task, unless there's some neat data table that can be sorted and edited easily.
