There should be an easy way to batch "enable all ICC profiles" for linked images in an opened document.
Today, the only way to do this is by changing each image individually. Alternatively, you can force an ICC profile mismatch before opening the file, and then enable all profiles while assingning the correct ICC, which it can lead to errors.

For those whose workflow is based on PDF/X-4, it is crutial to activate the ICC profiles for all the linked images in every InDesign document.
And since the default behavior for InDesign is to ignore the ICC profile while placing the image, it is frequent to deal with files with lots of images with ICC profiles ignored.

It should be piece of cake for Adobe to make this.
