Option to filter out NFTs not tradable on OpenSea in collection offer#41

Please add a checkbox that would enable filtering out NFTs not tradable on OpenSea in collection offer. It’s extremely frustrating to send a collection offer, only to get an NFT that is significantly reduced in value because it is flagged as stolen in other marketplaces.

The consequence of this feature not being implemented is that one needs to set a substantially lower value for collection offers - out of fear / risk of getting an NFT that is not tradable on other marketplaces / stolen.
