Having used the new assessment categories feature in v6.1, I have come across some limitations. Examples include the lack of subcategories and a few areas of the UI (and hence the UX) that could be improved. After assigning no less than 242 assessments (yes, I counted) to their categories I realised that we had already organised the assessments into existing frameworks which I'm sure could easily be adapted to organise the pool of assessments in a more structured and manageable way. So the feature that I'm asking for is the ability to select assessments by the framework they are associated with from a tree view of the current frameworks - as well as the categories for assessments which are not in frameworks.
