See my previous post on page 2.
PAYD was driven by popular demand. You were warned at the time that it would all end in tears. And now look at the mess (deliberate pun) you have gotten into!
The initial push for PAYD was via the AMPLT reports (and equivalents in other Services). the only way you could change things now is to SHOUT LOUD AND LONG. It would be a brave CAS who would totally ignore the clamour (mind you, I'm not sure that there are any brave very senior officers around nowadays - the good ones left when I did!).
Be careful to wish for things - your wish might be granted!
