Hello,
Another way to do this is; if you are comfortable using the FMC, (if you are flying a Boeing with FMC), just redo your arrival properly, then look at your descend page, look at your FPA, V/B and V/S. If your FPA is less than your V/B, increase your vertical speed to slightly below your V/S (e.g V/S 2349, use the vert speed to 2400fpm) This will result in your FPA matching or bettering your V/B. With that situation,you will be able to capture your path. Keep monitoring the V/S...
Hope that helps...
