There is no magic workaround here. It really depends on the image. You may have to make selections and create new spot channels or you could simply turn the whole thing into a duotone.

If you are lucky and she sent you in layers, and each layer contains information for only red or black portion, I would:
Turn off all red layers, save as greyscale PSD with transparency new file name. Open original.
Turn of all black and save as greyscale TIF new file name. Place red first, direct select, set to PMS red color from swatches. Place transparent PSD on top.
The duotone is also an option. I do not do these because they usually don’t work very well with my RIP.
Thanks for both replys. The file contains both text and images. I didn’t think there was a magic workaround but admit that I’m not a photoship wizard.
The duotone is an interesting idea.
The file is in layers but unfortunately each layer is still cmyk.
I think I’m going to send this file back to customer.
thanks for the suggestions.
Gary, sending back is a good idea.
However, as to your "layer is still cmyk", if everything is in layers, and you convert to greyscale with the sep information visible for each color only as two different files then it doesn’t matter if it started cmyk or not.
You convert the red info to TIF simply because you cannot colorize a PSD in ID, you leave Black as PSD (but Greyscale) so that you can maintain transparency.
If there is both "red" and "black" info on same layer, x-out and paste on it’s own layer.
This was always my work-round for customer supplied word docs that needed to be sep’d as well, only I would convert all red info to paper then plate, go back to original and convert all black to paper and plate. I know it’s not magical but it takes less than five minutes.
