Dead Pixel question - handling the images

So I looked through the images from my most recent shoot and found a small white cross on all the JPEG images. A sub-pixel has died

Luckily it's a 5Dsr so it's a small pixel. Unluckily it was in an annoying position on a dark subject, once the images were cropped.

So anyway I've updated the dud pixel map (select manual sensor cleaning then turn the camera off after the mirror locks up), which removed it (well, you know what I mean, removed its visible aspect). Actually it took a couple of goes before it zapped it, but it's gone now.

What I'd like to do is to use the new dud pixel map to re-process all my old images, rather than going one-at-a-time. I'm assuming it's in the (manufacturer-specific part of the) EXIF.

Has anyone done anything like this? How? Also any other suggestions? Would re-processing the Raws in-camera use the camera's bad-pixel map or the one (I assume) is in the Raw file?

BTW interestingly you get a diagonal cross in the SooC JPEGs and a vertical/horizontal one using DPP (which I don't usually use) so they presumably de-bayer differently, which is a little odd.
