Allow for batch processing, especially during onboarding

Please look into the feasibility of allowing for batching creating update deployments! As a new customer having to go through over 8000 applications one at a time is a very daunting task... being able to do even a page at a time would be very beneficial. OR on days when there are a ton of updates (the other day when there were 20 + firefox and thunderbird updates published for example) again it would be very beneficial to be able to select multiple updates and run them all through (assuming they are all going to the same groups).
