You can use logical operations on the filled ROIs:

1. Duplicate image, subtract 1
2. Create ROI 1, fill it and threshold (call it Binary 1)
3. Go to original image
4. Duplicate image, subtract 1
5. Create ROI 2, fill it and threshold (call it Binary 2)
6. AND Binary 1 &  Binary 2
7. Create ROI from the result using the new Create Selection and store in ROI
Manager
8. Go to original image and recall ROI from ROI Manager

I hope it helps.
