Thank you for the comments so far! Our use case is much simpler that we don't have multiple systems and therefore a data merge requirement. Ours is really more of need to get our data analysis better by getting multiple source data tables linked(joined) etc. For instance, we have a custom record for Inbound shipments (predates the NS feature) and would like to link it to receipt / fulfillment transactions and to item prices and so on. Even with the NS Analytics, we find it very hard to do within NS.
