ControlP5: Autopositioning of controls / controlgroups

I have a sketch that iteratively creates controls using addButton, which works great.

I want to remove these buttons and replace them with new ones, but after they are removed ControlP5 automatically positions them after the original buttons. I checked ControlP5Base.java and I think I can see where this is happening:
1. public Button addButton(String theName, float theValue) {
2. Button b = addButton(theName, theValue, (int) currentGroupPointer.autoPosition.x, (int) currentGroupPointer.autoPosition.y, Button.autoWidth, Button.autoHeight);
3. linebreak(b, false, Button.autoWidth, Button.autoHeight, b.autoSpacing);
4. b.moveTo(currentGroupPointer);
5. return b;
however I can't figure out how to reset currentGroupPointer.autoPosition.*
Here's my (simplified) code - you hit 'Create', then 'Reset', then 'Create' again:
1. import controlP5.*;
3. ControlP5 controlP5;
5. void setup() {
6. size(600,400);
7. controlP5 = new ControlP5(this);
8. controlP5.addButton("Create", 1);
9. controlP5.addButton("Reset", 1).linebreak();
10. }
12. void draw (){
13. background(0);
14. }
16. void Create (){
17. for(int i = 1; i < 40; i++){
18. String buttonname = str(i);
19. if (i%7 <= 0 && i != 0) {
20. controlP5.addButton(buttonname, i).linebreak();
21. } else {
22. controlP5.addButton(buttonname, i);
23. }
24. }
25. }
27. void Reset (){
28. for(int i = 1; i < 40; i++){
29. String buttonname = str(i);
30. controlP5.controller(buttonname).remove();
31. }
32. }
