Mountain run plus hiking periods

Hi All, I’m using the Venu SQ2 for running. For the mountain trails runs, during running, there are portions where I hike due to incline, then start run again and so on. However, the portions where I walk/hike are not registered in the running activity, so, I have less distance than the real one. Do I have a solution to add also the hiking periods, even the pace is much higher than the running ones? Thanks!
