I found out it would be helpful and faster to have a count of selected items, (similar to what we see in Excel as count of selected cells feature) for Timetables and Object Groups, as I've shown below. When there is so many members in groups or timetables and just want to do a quick check, having this count would make things faster and less likely to mistake the count. Not sure though if anyone else knows a quicker way to do the counting of members.
