RAW Details / DeNoise - Multiple Images

Hi,

Now that RAW Details and Denoise is in the main side bar rather than the drop down menu, I thought how do you select multiple photos to denoise together?  I then saw you can now apply these functions as part of Synch Settings, so think thats way to do it (even if a bit awkward having ot delsect all optiuons then click RAWDetails and DeNoise).     BUT, does the Synch Settings perform a seperate RAW Details and Noise Analysis for EACH photo seperately, OR does it simply apply the "adjustments" it determined from the photo you did first?
