Allow users to sell their NFTs at a fixed amount of dollars but in another token. E. G. $rei value is $1, i want to sell my NFT for $10, but i want to receive $rei. so i post my NFT dor 10 $rei. then $Rei goes up to $2 and my NFT post automatically adjusts to 5 $rei, keeping the dollars price but cutting the $rei price.

Thank you for reading.
