Hi all, I want to add daily high, low and other self created paramenters to the universe. Can I just add these parameters to the CoarseFundamental universe or I have to create a new universe?

 class CoarseFundamental {
public long Volume; // Traded shares
public decimal DollarVolume; // Traded shares x Price
public decimal Price; // Yesterday close price
public Symbol Symbol; // Asset symbol
public bool HasFundamentalData; // Whether it has fundamental
