Can I import 2D PDF drawing to a scale in an assembly drawing?

I use this program for water slide design. I often have to use a landscape or pool design from a builder to design my slides around. Can I import a PDF (a lot of the times this is all they provide) onto a top plan in the assembly to be able to design more efficiently without have to switch between programs to do this?

Any info or ideas?

Thanks
