Mark custodially listed assets

Hello.

I'd like to know which of my assets are listed custodially when looking at my wallet.

This is generally good knowledge to be used in, for example, rampages on the respective project's Discord in an effort to decentralized listing.

But also because many times, verification bots and other apps that use NFTs (e.g. Neoswap) do not detect custodially listed NFT ownership and it's never obvious that is the reason.

But naming and shaming must be the main reason.
