Can multiple Lync users all share their screens simultaneously?

Can multiple Lync users all share their screens simultaneously?

It is clear how one may share a single screen among multiple users in a
Lync meeting, but is it possible for every user in a Lync meeting to share
their screen simultaneously, wherein the presentation area would
automatically subdivide itself into a set of small tiles so each
participant can see every other screen? I am using Lync 2013.
