I read this from a PM client, and I believe it doesn't exist YET, but I will make a case for it:
If PPL have $$$ already in the System, and are going on a 2 Month Vacation, and They don't want to be $$$ for services they will NOT be able to use during that time, Perhaps putting that in Self-Serve so that they can put their A/C on Hiatus, And Not be Charged
So, if you had $130 in System, and your Rate Plan(s) was $30, and you were going on a 2 Month Vacation, being able to put A/C in Hibernation Mode and retaining the $130, or even a Small Hibernation Fee, Like $10-$15, can certainly be more preferable to paying Full Rates for Services you can't enjoy if on Vacation
