Trend: Add Dynamic Search Criteria
Allow dynamic search criteria to be added to a trend so that it can dynamically display data from assets based on the specified search criteria (attribute values, attribute name, attribute category, etc).
We monitor some buildings at different sites, and have climate sensors in each room. We want to display all temperature measurements from all rooms in a building in one trend, regardless of the number of rooms.
Some buildings have 20 rooms while others only have 3.
Today we're building the semicolon separated list of paths to the attributes using PI SQL, and appending that to the PI Vision adhoc trend URL, in order to accomplish our goal. Many steps for a simple task.

Collections and Asset Comparison Table are a big step toward meeting this, but the example given suggests a single trend/graph with multiple traces, each trace representing the MW produced for an asset. This specific functionality has been requested here - https://feedback.osisoft.com/forums/320517-pi-vision/suggestions/12903429-asset-comparison-trend-with-multiple-elements-wit
Be able to easily create an asset comparison display where the same attribute on an asset is compared against other similar assets (for example, based on template) over a time range.
For example, compare the MW produced on all Wind Turbines over the last day, which on a trend the traces would be the name of each asset.
