I'm wondering if it'd be possible to merge all commands for ERC-721 and ERC-1155?

We could probably do something, although the most problematic part would be exposing extra flags to the commands (e.g. exposing amounts flag for ERC-721 or token ids for ERC-20, though we could validate it). Not sure if is it possible to register a flag "dynamically/conditionally", namely only after we tested the value of some other flag.

However, maybe do it as a separate PR, when all these are in place? WDYT?
