FTP Prediction Question

I had a feature request to push the FTP predication to the end of your planning window, so you can always take advantage of seeing the effect of changes in your plan to your fitness.

In lieu of that, has anyone figured out a clever way, where let’s say my prediction is 2 days away, but I want to move things around and see where my FTP will be in 30 days from now without waiting however long until my detection date?
