Hi, recently, I noticed that the selection of cryptos available for trading on Coinbase has been updated to include a number of currency pairs that were previously unavailable to trade using QuantConnect.  Some of these currencies include Solana and Mana.  However, when I try a live-trading algorithm, there is no price data for Solana and Mana from the COINAPI for coinbase.  How do I use an external data source for the algorithm so that it will be able to trade based on Solana price points?
