Apple

I am working on PackageMaker and build a installer which will install some applications to user specified location. I am using the command line utility to build and run the package from package maker. But i am facing a problem with this. When i open the .pmdoc file, i found the "relocatable" check box is checked every time. So i have to uncheck all checkboxes , save .pmdoc file and run command to build the package every time. I want to turned off all checkboxes by default when i open the .pmdoc file. So that there is no need to uncheck all check boxes manually and resave the .pmdoc file .How can i solve this problem.
