Update the dataset list with a new data import

I can manually change the entire contents of the datasets if I want to. The link to the pin remains intact.

As a user, I’d also like to be able to overwrite the data with a more up-to-date Excel list. To back up data, there could simply be versions so that I can jump to the latest version at any time.

There could also be a preview when updating, so you can see the old list compared to the new one and decide whether the content is being updated correctly.
