Add same fee to all products

Hi. I’m selling tickets to event through Modern Tribe’s “Event Tickets Plus” plugin. It creates a Woocommerce product for each ticket and have to create (and recreate) tickets for each event.

I want to charge a universal ticketing fee for each ticket (for example, $2 per ticket).

Is there some way to simply set up this plug to charge $2 for each Woocommerce product by default? The alternative is time-consuming as I have to create a ticket, go to the associated product and add the fee to that one ticket only and then repeat for each ticket for each event.

Thanks.
