Image filters on poses

Hi

I have a character with two poses. I want one to be 'normal' and the other (duplicate image) 'visited'. The 'visited' needs to be greyscale. However when I apply a greyscale image filter to the visited pose the 'normal' pose also goes to greyscale.

I think it should be possible to have one greyscale and the other not but I cannot make it happen!

I have tried swapping to another pose image from the 'assets' for the visited pose. This works in that different image is accepted by Captivate but the greyscale filter still appears across both poses if applied.

I hope I have explained the problem clearly.

Thanks in advance for any ideas
