How to get Summaryinfo value other than Sldworks default property.

Hi,

I've tried looking for an API which can get the Summary information which we can get from File->Properties->Custom.

The SummaryInfo Property can give the SolidWorks default Properties (swSummInfoField_e) only.

Can any one suggest a way to add, edit and get the user defiled property. I dont want config specific custom property.

Thanks in advance.
