Describe the solution you'd like

As good as the CCXT unified id is, it's not enough for all scenarios.
Is it possible to add cmcId and coinGeckoId to currencies?
Instead of adding aggregators as Exchange, add their ids to existing exchanges.
Is it less or more work to do?

Hi @bozorgmehr96 I'm not sure what having different aggregator ids in the currency structure would be required for in CCXT.

As good as the CCXT unified id is, it's not enough for all scenarios.

Could you share the scenarios where the CCXT unified id is not enough?
