Yes, you can add multiple widgets on your site. That being said, those Widgets won't be able to target the same pages.
Here's how you'd want to set this up. First, head to your Tada Dashboard by selecting Email Pop ups Exit Game- Tada in the App section of your Shopify Dashboard.
Next up, either create a new Widget or select the one you'd like to customize.
In the top Tab menu, select "3. Widget" and then select on which pages or products you'd like your Widget to show up.
Make sure to target your Widget to a different page or product selection that any of your active Widgets. If two Widget target the same page or product, only the most recently edited one will display.
