Replacing a dataset from a new workbench (secondary laptop)

Hi all,

I recently got a second machine for the purpose of automating reports, including Workbench pushes. 

I setup a bunch of datasets on the new machine, and named the tables identically. However, when they make their way to Domo, I see the exact same dataset twice (one old one and the newer one).

I suspect Domo actually uses the Job ID or some other unique identifier to upload into Domo - different Job IDs would result in seperate datasets even though they should be replaced.

Any thoughts on how I can replace those original datasets with new ones originating from my new laptop and new workbench? The alternative - changing the source of every card - will not be feasible! 

Any ideas would be appreciated
