Can we have a "select all" button in the updater

Sometimes if I haven't used my computer for a long time there will be a long list of updates for my Portable Apps. If I just want to quickly update my portable Firefox browser so I can jump on and do some internet banking safely, I have to manually deselect all the other apps one by one which takes an eternity, or else leave it with all apps selected which will take ages on my slow connection.

Could we have a checkbox at the top that allows us to easily select all/deselect all apps? The way Windows Explorer and lots of other apps do it:
