Add 'Snapshot Value' column option
When retrieving all PI points, there should be an option to also include the Snapshot value. Currently, a user must use other means to retrieve all current values and then merge the two together.

There shouldn't be any need for any merging step. Import your data using PI Builder. In a new column in the imported table, use the PI DataLink function PICurrVal to retrieve the snapshot value.
