How do I add Algoseeks free cloud data of US Equities as my universe here for backtesting ? I want to select all US Equities with market cap of more than 100 million dollars as my universe 

I am new to the platform and I am unable to start properly as I am unable to select my universe . The only method I got to know is by adding individual stocks which I dont think will fulfill my purpose. 
Can you guys please suggest some resource from where I can start as I am unable to understand it from the documentation
