FIltergraph~ reverts to Display Mode

Dear All,

Is there any way to load a set of coefficients into filtergraph~ without it reverting to display mode? I want my application to open with a preset filter setting, to display that setting in filtergraph~, and to allow the user to subsequently edit those filter settings.

I have searched the forums and found no answer other than one that implies this should be a feature implemented in 5.1.

Many thanks in advance,

Nick
