See the data which is pulled when updating edition from remote connector

Is your feature request related to a problem? Please describe. When I hit the "load data" button and pull data from e.g. Open Library it just gets merged into the instance without a chance to see which data is pulled. (Is it only IDs? Is it Text? A cover? Maybe a better cover resolution available?) I want to see which data would be merged into the instance and acknowledge

Describe the solution you'd like After hit "Load data" show the data which is loaded. In best case, show beside which data is already on the instance.

Describe alternatives you've considered Hit the button and remember which data was there before.
