Software Deployment

I'm packing our product in a .msi. Our product is used by 9 different companies. Every companie have there own files that need to be added to the Base product. I have found out that making a transform (.mst) for every company are a very good way of working.

My problem is, that every time I do a change in my .msi. IE. add a file, remove a file or some other change. All my .mst is worthless. Because a .mst is only working with a special .msi. So after I have changed my .msi I have to rebuild my .mst.

I'm using Wise for Windows Installer 6, to create my .msi and .mst. I have build my own installation program, so I install my .msi and .mst quite, so I'm not looking for a tool wich can change the GUI for the user.

I'm looking for a tool wich I can easy add/remove files from my .msi as making my .mst. The work done to build the first .mst should be able to "record", so I can "play" it as making a new .mst, to the new .msi. Or if I could add the files recrusive, I drag the top folder and drop it in the right place, and when the rest of the files will be placed in right place.

If there is any tool out there it would save my about 2 ½ hour of manual work every time I have change my .msi.

Thankful to know if you know of any tool,
