Bridge - BATCH managing file's settings snapshot?

Hi,
In Bridge - ACR, Looking to batch save the RAW file's settings snapshot of individual files?
Every image has their own setting, and i want to:

1.Batch save each files custom setting into snapshot (last panel in ACR)
(currently i've thought just to batch copy the XMP files to a temp directory)

2.How to manage different versions (batch change snapshot / versions) of the RAW settings of all files?

Thanks!
