Is there a Named Expression to check for a specific sheet name?

Question

I am looking for info for a Named Expression that determines if a certain Sheet model exists. For example, "BorderSheet" 
 Or if this isn't possible how about a Named Expression to determine if a specific TagSet exists in the file? 
 Thanks, 
 Regan

This will returen true if the active model type is a sheet and the model name is "BorderSheet" 
(Session.ActiveModelTypeIsSheet() and ActiveModel.Name="BorderSheet") 
 
But I do not know of any way for a named expression to loop through all the models in a file. You may have to write a custom vba to run the named expression on each model.
