Add support to copy multiple containers

[lokijota]

Or, at the very least, when you get to the final screen after a copy, enable Previous button so that you can go back to the previous screens and just edit the names of the containers.

Apart from that, excellent tool. This could/should be added to ADF, pre-creating containers when copying CosmosDB to CosmosDb is a waste of time.

This feature should be implemented. It should be must have feature.
