Saving standard parts of Product assembly in Catalog folder

Hi,

I need to save few parts from product assembly in the Product tab and few standard parts in Catalog tab.

Where/How can I set the location of these parts when the assembly is saved to ProductPoint?

Toplevel.asm -----------------------> to Product "A" in WPP

----body.prt--------------------- >to Product "A" in WPP

----cap.prt --------------------- >to Product "A" in WPP

----screw.prt--------------------- >to Catalog folder "screw" in WPP

This screw.prt, I am saving for the first time in WPP. There can be few other catalog components in assembly created for first time which need to be pushed to Catalog folder while saving "toplevel.asm"

Thanks,

Sanjay
