Can I still use other functions on my Huawei Watch Fit 3 while it's in training mode?

So I have a Huawei Watch Fit 3 and use it to collect data during a training, but while the training is active, I cannot seem to use other features of the watch, like setting an alarm or starting a timer. I'm missing especially the latter, since I want to do stuff like "run for 3 minutes, then walk 1 minute, then run another 3 minutes, ..." or timing circuit training which could make good use of the timer/countdown functionality.

Am I missing some feature or some secret button/knob operation which allows me to do non-training/non-music stuff while training is active?
