I think I understand what you mean.
What is your data source for the Power BI report? What you could do, though it might take a little work to set up, is this:
1) Add the fields from your canvas app that you want to capture into the same data source that the Power BI report is connected to.
2) Use a Patch function to write to the data source when the user uses the canvas app.
3) Add these new fields to your Power BI report.
So the user makes changes in the canvas app, those changes are written back to the same data source the Power BI report is connected to using a Patch function, then the Power BI report reflects the changes.
Let me know if that helps.
