Yes. If you read a mesh from a file, the "Show by entity number" should
act as an on/off filter on the physical entity numbers. To show only the
physical region 99, you type

'*' <enter> (this toggles the visibility of everything. And since
everything was initially visible, it hides everything...)
'99' <enter> (this toggles the visibility of region 99)
