In-game panel OFP Editing


I am using the Navigraph MSFS In-game panel to display charts and my Simbrief OFP. However, I miss a feature to write text on the OFP (ex. when I want to write the actual fuel burnt at each waypoint on my OFP). Using the annotation function to write text on the OFP is not easy, would it be possible to add a feature to be able to write text annotations by using the keyboard ?

Best regards,
