show hide unplace annotation

[MarcelSt-Germain]

Be able to show all unplace annotation with a clic instead of for each element could be verry useful.

Marcel, what version are you working with?

In ArcGIS Pro 2.0, when working with annotation symbology, there is a check box to Draw unplaced annotation.  

Is that the "show/hide" functionality you're requesting?
