Add Events to Groups

Is there a way to add a bunch of events to groups when the events are already made outside of a group, besides dragging and dropping, because dragging and dropping does not seem to keep events in the right order and seems to take a lot of reorganizing. I made the mistake of not grouping a lot of events and now i want to group them just wanted to see if there was a way to select a bunch of events and group them at once to keep the order, a right click and add to group function would be nice.

Or you could try shift clicking the top and then bottom one and drag the whole thing into a group.

thanks exactly what i was looking for, i sware i tried shift alt and ctrl + click but i didnt try clicking top and bottom, thanks!
