stamps.com ODBC import customs info

This is a specific question for [login to view URL] software. I use [login to view URL] shipping software to print shipping labels. All my customer info is stored in an excel file. I am able to use their ODBC batch function to import most info such as name, address, phone, email, weight etc. However, for international orders, I couldn't import the customs info including item description, value, and merchant type. Each batch file is associated with an xml template under appdata folder. Please check the attchments for the xls and xml file. What I need is to import the customs info automatically from the xls file to stamps.com. Thank you for reading this post.
