The Earnings Calendar gives you the ability to filter the tickers by either Universe, Quotes List, Portfolios and/or Watchlists.
The Tickers to Include pull down menu is available at the top of the calendar in the blue bar. As you can see in the screenshot below you can select what you want to include in the calendar.
Selecting Universe will give you the option on which universe you want to include in the calendar. You have the choice between S&P 500, Major US Listings, Most US Listings, or All Exchanges, similar to screener options.
As you can see in the screenshot below you will have the option to include portfolios and/or watchlists and you can select which ones you want to include in the calendar.
