Is there a way to get CorelDRAW 2018 to use more cores?

What the question says. Is there a way to get CorelDRAW 2018 64 bit to use more than 1 core for large processing tasks? I get that it can use more than one core for background tasks, but I generated a 1700+ page mail merge today that took 10 minutes using just 15% of my CPU. I'd LOVE to boost that up and use half of my CPU even.
