Already aware of these sources. Didn't solve my prob. Thanks.

Airdrop is baked into the macOS—there is no user preferences for changing the location outside of the Downloads folder.

You can however  submit your Apple Feedback http://www.apple.com/feedback

I always prefer to receive downloads to my MBP desktop rather than my downloads folder. Is it possible to set up that preference for AirDrop? Thanks.
