How to run "convert colors" and "map colors" fixup in one preflight profile?

Hello,

we want to convert absolut colormetric sRGB files to CMYK.

The fixup "convert colors" does a great job.

But we have 70 special RGB colors we want to convert to exact CMYK values.

This 70 colors are Pantone colors, coded with their RGB value in the pdfs.

So we made a "map colors" fixup, which can map this 70 RGB values to the official Pantone CMYK values.

This part is also working fine.

But combining this two fixups in one preflight profle does not convert the colors as expected.

Our goal would be to map this 70 colors exactly as defined in our "map colors fixup".

And all other colors should be convertet absolut colormetric from RGB to CMYK, as defined in "convert colors fixup".

How can we combine this two fixups, so that one is handling this 70 colors and the other one all other colors?

We need a solution to convert over 20000 files.

Thanks for your help
