Best approach to generate WebID 2.0 from PI Vision symbol DataSource path strings

Currently looking into ways to save a few seconds when initially loading a PI Vision display with a custom symbol (or many). Not needing the round trip to get the WebID's would save some time, so let's move on to WebID 2.0!

I know, a batch call could both get the WebIDs and the data, but i already have a complicated multi-stage batch call so i don't want to overcomplicate that one. Errorhandling is a pain with these batch calls!

 

But a bit uncertain how to proceed:

 

Any suggestions / experiences? (or source code... ). Did not see a PI Vision custom symbol yet that leverages the WebID 2.0 for PI Web API calls
