PIP continuation

My wife Shirley is the claimant and I do the writing

History: After not being able to work (she was a nurse 30+ years ago) she was put on the old incapacity benefits being rechecked on several occasions during that time to make sure that she still qualified and passing the tests, a couple of years ago she was asked to fill in forms to move from Incapacity Benefit on to ESA. Met Atos for a 15min meeting and was told she was fit enough for work. We appealed, had a 10 min talk on the phone and Atos said she was fit to work. Took it to a tribunal and after 10 min in the room was told that our claim was upheld and that ATOS should not re-examine for at least 2 years which was a great relief. However this was short lived as after the year was up, she was then informed that as she was not in a work group, that was it times up no more money. she went into a depressed state and would not look to appeal yet again. She could not look for work even if she could do it (because the tribunal had said she could not work for at least 2 years) so no job seekers allowance. We looked at the process of getting into the work group but as I said, she lost the will to go forward with this. We did contact some other groups for assistance when we were doing the tribunal who told us about PIP and going for a Blue Badge.

we applied and won and Shirley was awarded the standard Pip for both Mobility and daily living about 2 years ago (and we got a blue badge award at the same time).

We have just been sent forms about looking at her personal payment again.So as nothing has fundamentally changed we are going through the questions as we speak.

So to my question: Can anyone tell me if there is any sort of short cut to say 'nothing has changed' to save having to do this? After all this is not a new claim but a continuation.
If I have to start all over again, is there any info and advice that people can give (outside of the Members guides that are on the web site) to help with a continuation not a new claim?
