How Can You Tag a Custom Coin as NFT so it classifies sale properly for taxes?

Hello, I scanned my NFT wallet with the NFT scan tool in cointracker. Past NFT sales don’t show up. I have recorded those with custom tokens. How can I tell cointracker that custom coin is a NFT - it needs to be tagged as a NFT sale so it mark that properly on the Tax Form 8949 - it needs to be tagged with a C indicator on the 8949 record.
