The following is is very ugly :-) and non-standard, but it is better than
nothing:

You can decode the ROI into a string and insert it as metadata of a tiff file.
You then will need another macro that reads the metadata and creates the ROI.
I used a similar method to store LUTs in a stack (so each image has a LUT
associated).

Perhaps the easiest is to save the ROI via the ROI manager with a same name as
the image, so you can process any image and you can derive the name of the
roi straightforwardly.
