Load calculation / data upload from other apps

Where do I choose the different software apps to upload my TSS / Load data after a ride. It appears my outdoor rides are calculated by Intervals in a certain manner (which is fine), but the indoor trainer rides are taken by Intervals strictly as calculated by Training Peaks. Why does Intervals not calculate the Load of the indoor rides as well (only doing it for outdoor)?

Intervals.icu doesn’t get any information from Training Peaks. It calculates TSS using the same formula as TP but excludes coffee stops. This might be why your indoor rides have the same load but outdoor rides differ.
