Revit 2D Symbols - Visibility?

[Anonymous]

Afternoon , hoping I can get a little advice on symbol creation.

I've set up a family to contain all our electrical switch symbols. In the family types I've used a yes/no parameter for each switch to control the visibility. It works really well and when I load it into the project I can use the drop down menu to cycle through them all and each one shows up properly.

But when I've got edit family open I see every symbol on top of each other all at once. Is there a way I can control what I see in edit family so I can tweak one symbol without seeing every other one? I can't seem to find a way to show only one at a time.

Having every switch or every schematic valve symbol contained in one family is really useful so I'd prefer to keep doing it this way if possible, rather than individual families.

What you want, preview visibility function, is been made available in the R2 Update of Revit 2016.
