I don't particularly disagree with anything that has been said by others here, however, my inclination would be to say no, for the simple reason that it is not necessary. If you ask ten people to write a letter on a particular topic, you will end up with ten completely different letters. The fact that they are different doesn't, in itself, make any of them incorrect. You employ a clerk as a professional officer of the council and must trust them to undertake the role in accordance with your wishes and to the best of their ability.
Micro-management is fraught with risk and may imply a lack of trust. It can snowball out of control very quickly. In an extreme case that I'm currently embroiled in, a retired councillor started popping into the office to see the Clerk from time to time, then made it a daily visit, then sat behind the Clerk for the whole of her working hours, then decided it would be beneficial to confiscate her laptop every Friday afternoon and take it home for the weekend to make sure she was doing what the council required. Needless to say, the employment tribunal isn't going well for the council!
So, returning to the original question, my advice would be that when your county councillors start reading every key item of correspondence issued on their behalf, you should do likewise, but until then, why not devote that time to creative thinking about the needs of your community?
