Feature Enhancement. Hidden Group Members Reappear on Grid Import.

[PhilMassey]

I have a Grid View Group containing my Motion effect rows, about 30 of them. I hide the Member Groups and Props to keep things tidy so all I see are the Motion Rows. 

If I import a Grid View, all the Member Groups and Props reappear and I have to hide all of them  again one by one for each sequence.

Is it possible too either not have them reappear if previously hidden, or have a "hide all member props" command to hide them all at once?  Perhaps the condition could be saved as a part of the Grid View Export process, since its is not currently saved.
