Here's a little preview of the integrated app - the folders tab will be the same, with all the changes on the Options tab.

You can select the mode of operation - ppmcentre only, RGBSplit only, or both. Set the ppmcentre options you want. Change the RGB Split default folder names (if you want). Go to the Folders tab and press Process. The app will run ppmcentre on the folders you selected, RGBSplit will then process the resultant ppmcentred bitmaps - all as a 'batch' process, so no user input required.
