Edit all events in foldermap at the same time?


I have several drumtacks recorded, they are all in a foldermap. I highlite the foldertrack and doubleclick. (PC DAW) Now I want to, lets say, to make hitpoints to all tracks and at the same place at every track of course.

My problem is that I can only edit one track at the time in the editwindow. I have to scroll to each and every track and make hitpoints wich is timeconsuming…

How can I make edits that effects ALL tracks in my folder at the same time?
I am of the impression that putting tracks in a foldertrack would alter them as one track so to speak…when I highlited the orange square . Sometimes I dont know if I Am doing wrong or if it is some bug…
Please help! Micke.
