USING PHOTOSHOP AS A BITMAP EDITOR FOR COREL DRAW

Somebody can help me making this possible in a not to technical explanation.

I saw this USING PHOTOSHOP AS A BITMAP EDITOR FOR COREL DRAW  https://www.youtube.com/watch?v=4jojXi5k0VA youtube movie and I would like to work with photoshop styles for my work I create in Coreldraw x7

I am wondering how to get the link from corel and photoshop up in the corel bar.

I hope somebody could explain me, because it will be a real time saver!!

Thanks, Caroline
