@Kelly149 prices are updated nightly, and vary a lot night-to-night, so I don't think manually copying would be feasible.
But Host Tools (hosttools.com) is a very low-cost tool for automatic messaging and price management, and it can now copy prices from Airbnb to Vrbo, for exactly this scenario. I use Host Tools for automatic messaging on Airbnb and have found it to be a reliable utility.
Caveat: Wheelhouse actually varies pricing by channel, since markets and fee structures differ. So by copying from Airbnb to Vrbo you would lose that fine-tuning. Still might be a significant improvement, though.
