Bulk migration from one asset to another

Bulk select a large amount of assets from a layout. Choose migrate and select another layout. Assign fields from the source layout to the destination layout. Receive a warning if source fields are left unassigned that data may be lost with a summary of how much will be lost

Imagine: an asset layout is filled with items, then it's decided to split the layout into 5 separate groups. This solves having to recreate everything single asset over again
