Red Spitfire Driver,
Perhaps unfortunate that your post followed mine. As always, I am quite calm enough. Aside from that, if you are as you suggest, can I have a go, please? (Never flown a Spit).

I think the length of your post, and the detail required to explain, highlights the inefficiency of the set-up.
Many AFS are first aid-trained, yet if I am on the ramp with a medical emergency (three timnes in the last four years), they are not even put on Local Stby, as no specific request for AFS attendance has been made. This is scandalous. My advice/suggestion above stands as it is specific and ensures the attendance of an ambulance when one is needed. BTW I am an ex-ATCO.
I would add to it that it is worth telling ATC that you also require AFS attendance to ensure that these competent and trained people will be on hand, rather than sipping tea whilst yur pax dies simply because the procedures do not require their being called out.
