It would be useful to be able to specify that an activity includes segments of multiple types. I have segments specified for walks but I like to class scrambling or rough walk activities as hikes to single them out. Hike activities may include walk segments but when this happens the walk segments are not associated with the activity. Similarly hike or walk segments that are followed on activities I class as rock climbs are not associated with the activity. A day rock climbing could easily involve segments of mountain biking, hiking and walking. It makes no sense to recreate the segments and falsely call them rock climbing just so they are recorded. Hence It would be useful if it was possible, for each individual activity, to be able to specify what segment types should be included. A default of just the main activity type with an option to select others would be ideal.
