The [Power Search] function in the KVS Tool is designed to locate difficult-to-find Award Availability across a long date range. It is not designed to provide long lists of easy-to-find Awards.
However, once the [Power Search] locates Award Availability, you can use the [Ctrl+P] shortcut to take a snapshot of the results and then click the [Power Search] button to continue the search going forward (and then repeat the process as many times as needed).
I don't think that producing a list of difficult-to-find Award Availability across a long date range is incompatible with its designed function which is, as you state, to "locate difficult-to-find Award Availability across a long date range."
Just because I'm looking for a difficult-to-find redemption doesn't mean I want only one date, the first date.
Just a suggestion for an enhancement. One which I would find very useful.
