PIP - whether to challenge?

Hi! So on PIP review (allegedly paper based but lengthy telephone conversations with 11 questions), my daughter kept her enhanced daily/care element and was awarded enhanced mobility this time. However, there are some descriptors which I challenged from first award, notably social and communication issues (she is autistic, ADHD) but has still scored no points. I supplied evidence (eg SaLT report, DSA report, info from GP and psychologist) but still no points. I explained her difficulties but as she is not aggressive (which was the only thing assessor seemed interested in) and because she went to university, she's deemed not to have any issues. Allegedly I didn't produce evidence - which I did - and when I asked in the assessment what additional evidence they wanted, I was told I was the best source of evidence! I am not sure whether to challenge, clearly i don't want a reassessment of whole claim. But I am concerned that 1) no challenging will be seen as acceptance for next review and 2) it means that her PIP report can't be used as proof for some other benefits eg Nimbus card. Is it possible to lodge a 'disagreement' with DWP without invoking a MR/reassessment?
