It would be extremely handy to have a column of check-boxes displayed on certain reports. I have an "UnBlocked Events" report that I created for IPS. I can easily block individual Sids from that report, however it takes IPS a significant amount of time to save settings each time I block a Sid. A column of check-boxes in the report would allow me to check each Sid that I want to block and save the changes all at once.
I'm sure this would apply to other reports as well, but for me, IPS is the big one.
