Faster Constraint Add

I have a rather massive property grid, or I should say one with thousands of parameters.  Is there any faster method of adding multiple constraints (like an override with a string[] passed in)?

            item.Constraints.Clear();
            int i = 0;
            for (i=0; i<constraints.strings.Length; i++)
            {
                item.Constraints.Add(constraints.strings, i);
            }

Right now this seems to be the only method, but I'm sure internally it could be performing this action a lot faster.

Apologies if someone has already asked this.  I don't see it mentioned in the forums.
