Sheet metal part to dxf flat pattern macro question

Hello All,

                I have modified a macro written by Deepak Gupta. It is a macro that takes a Solidworks sheet metal part and exports it in a flat pattern to a dxf. I have added the revision level to the filename. (See Below). The dxf file is made in the same subdirectory. My problem is when I try to redirect the dxf file to another subdirectory I lose the part number portion of the file name.

I want to add to the macro a popup to chose between to subdirectories. I am not new to the forum, but I am to making a macro. Any help will be appreciated.

Sample filename: THIS-IS-A-DXF-TEST_Rev C.dxf
