Save incremental tempo changes in the library

It would be great if the app allowed us to save incremental tempo changes directly in the library. This way, not only static tempo settings but also progressive tempo adjustments could be stored, recalled, and reused easily. For example, I would like to save a practice routine where the tempo increases by 5 BPM every few bars. Being able to store this kind of incremental tempo setting in the library would make it much more convenient to practice gradual tempo increases without having to reprogram them every time.
