I don't have any specific advice for you, but I do know that as a teacher, any child with allergies had their photo and action plan posted in every location they visited at school ie classroom, specialist rooms) plus staff room and office. The action plan had a set format, but was made up by the school. So, the parent provided information and the school rewrote it into a plan that was displayed for staff. If that's the case, surely whatever format you provide the info in (as long as it's been signed off by your GP) would be fine?

Oh, and intolerances (or non-life threatening reactions) were also listed on the action plan.

I feel for you - it must be tricky organising and figuring all this out.
