Attribute Category Filter URL Parameter
Add support for an attribute category filter in the Ad Hoc display URL parameters so that Ad Hoc displays can be constructed with only relevant attributes displayed.
Customer Issue: Sometimes it is useful to display only a subset of attributes from an element in an Ad Hoc display, such as when there are a mix of static and dynamic attributes, or when a only specific aspect of the asset is of interest. Currently the two options with the DataItems parameter are to specify the element to show all attributes (DataItems=\AFSRV\AFDB\Element) or specify the attributes explicitly in a semicolon delimited list (DataItems=\AFSRV\AFDB\Element|Attribute1;\AFSRV\AFDB\Element|Attribute2; … ).
Note: This was previously Enhancement 119762.
While we appreciate the interest the community has for this suggestion, we have decided to decline this item in favor of other high priority work the product needs. Thank you for your feedback, and please continue sharing suggestions for how we can improve PI Vision for you!

Currently, you can use path syntax for collections and filters (see links to documentation below) with the DataItems query parameter, but only the first item in the collection (i.e., Index=1) is returned to the display
This will trend the 1st attribute whose category is KPI, but it would be preferable to trend all attributes that have an attribute category of KPI.
