Hello Guy,
you could try ObjectJ, which allows non-destructive marking that is aware of stack slices and hyperstacks, and bundles rois and other objects across many images into a single project file.
Look at the tab "Tutorial": it mentiones (segmented) lines and points, but also ROIs an polygons are supported.
 
- An ImageJ roi can be converted into an ObjectJ Roi via menu ObjectJ>Objects>Create Item From ROI.
- An ObjectJ ROI can be converted into an ImageJ roi via the "Object To Roi" tool.


Under the tab "Examples", there is also a worked out example "Oocytes" that includes a movie showing creation of automatic and manual non-destructive ellipses that are stack-aware.
