I have found a workaround, from [this post by u/stevenson](https://forum.inductiveautomation.com/t/perspective-barcode-scan-context/51596/5). In my implementation, the view that needs data scanned into it from the session event first sets a session.custom property to the value of the return ID I wanted as context for the barcode scanner event, then the barcode scanner reads this session.custom property to provide the correct returnID in the payload of the barcodeScanned message.

I think that the session custom variable is an inelegant solution, but the only one I can think of without a way to activate the session barcode scanner using a system method.
