1) Not available currently. A request is in to have this functionality added.
2) I would check into transforming those UnDP values during collection
3) UnDP tabular resource doesn't allow clicking currently. Not sure if that is added as a request yet but that would be pretty cool if you are collecting historical information.
2.) Hmm, what can I do this, also can it say MB or GB at the end?
3.) Is the UnDP tabular resource the only way do do this or can I use another view type?
