Manually modify activity

Unfortunately my Wahoo went out of charge in the middle of my workout, so it uploaded an activity that is only half of what I did.
Is there a way to manually modify the uploaded activity? (I know timing and power of the intervals I did after the switch off).

Thank you

You can edit Distance/Elevation gain and Load from the activity summary.

You can’t ‘extend’ the power graph because there’s no timeline.
Another possibility is to leave the partial activity as is and add a manual ride with duration, distance and load for the lost part.

Ok…thank you for your tips.
