Set image colour settings for multiple images

Question

In my workflow I place (Adobe)RGB images into InDesign. PDF export takes care of the RGB to CMYK conversion (convert to destination with preserve numbers).
However this uses the default rendering intent for every conversion: relative colorimetric.
For images, i want to use perceptual.
Is there a way to quickly select all images and change the rendering intent?
All the images have the same ojbect style. Unfortunately i could not find a way to couple the rendering intent to the object style.

You can do it it via Assign Profiles...
It can also be scripted, something like this AppleScript:
tell application "Adobe InDesign CS6"
    tell active document
        set imgs to all graphics
        repeat with x from 1 to count imgs
            if class of item x of imgs is image then
                try
                    set image rendering intent of item x of imgs to perceptual
                end try
            end if
        end repeat
    end tell
end tell
