How to create more than one save point in session

Question

Hi,
I'm using Jdev 12c.
I'm trying to use the SavePoint in ADF. When I try to use createSavepoint() function of SavePointManager to create savepoint I met a problem is only one row of savepoint is created in DB (table ADF uses to kept the savepoint in DB) and it overrides the old row whether how many times I uses createSavePoint() function. I want to when I call createSavePoint(), a new row of savepoint is created instead of overriding . Below is my code:
        ControllerContext controllerContext = ControllerContext.getInstance();
        String savePointId = null;
        if (controllerContext != null) {
            SavePointManager savePointManager =
                controllerContext.getSavePointManager();
            if (savePointManager != null) {
                //creating the save point
                savePointId = savePointManager.createSavePoint();
                //putting the save point id into session scope
                ADFContext.getCurrent().getSessionScope().put("savePointId",
                                                              savePointId);
Could anybody help me this problem?
Thank you very much.

Dear Frank,
Thank you so much for your answer. Beside the save point functionality to save the state and values on the screen, do you know other ways to do the same function? Once again, thank you so much.
