Within the family editor, I'd like the ability to select multiple parameters and change them from Instance to Type or vice-versa. Regardless of the formulas within the parameter values.
It's a pain to have to remove formula's within parameters to convert them from one to the other.
"Yes, Revit, I know that I can't change this parameter to an Instance parameter unless I change the 3 others using it in their formula, but I can't change those unless I change this one" <--Which results in me removing all formulas, changing each one by one from the Types dialog and then re-inputting the formula's.
If it would allow me to change them all in one process, that would eliminate the problems of instance parameters being used in a type parameter formula, etc. etc.
