There are some now that will take you there such as the weight and allergies. It would be nice also to add a link to take you to the advance directives question to change that, behaviors, multi-drug resistant organisms, chief complaint, isolation precautions, and code status. It would be nice if there were these links so we wouldn't have to go to demographics < encounter just to change one thing if that were the case.
Note that clicking the patient Photo area gives immediate access to the Encounter Demographics page to update those areas.
