Is there dual monitor option for Adobe Photoshop Lightroom 5.5 (Cloud-based)

Hi,

Due to the confusing name changes on the Lightroom products, I'm having a problem finding an answer on any of the fora!  

Currently using the programme in the subject and would like to use 2 monitors on my iMac setup.  

Is there any way to do this yet?

Many thanks in advance!
