Request - Add Arbitrary coins to portfolio, integrate with 3rd party data provider for information instead of needing a node for each asset.

I posted this message to Reddit and decided to try harder than that so I am posting here now.
https://www.reddit.com/r/ledgerwallet/comments/knpk34/idea_for_ledger_live_must_have_feature/

Concept:
Allow users to add any coin supported by data handlers such as CoinGecko or CoinMarketCap or {INSERT ANY}.
An End user would provide the # of coin or token they hold OR in some cases we could fetch their balance using the many block chain explorers, maybe we could offer to let them specify their public key and we could fetch their real-time balance. (ideally due to staking or external transactions would constantly require us to update our own balance manually) I would however be very happy if I could at the very least specify my own balance.

Ledger Live could utilize a 3rd party API for real-time pricing information without the complexity needed for full send / receive for fully supported assets.
We could make the asset look different in the list of the portfolio page so to differentiate the type of asset (fully supported vs unsupported).

This would solve another request for adding any ERC20 tokens.
