I just did it for my app and it works;
Label and button are in the colum, the label positioning is absolute and you can offset its edges to make it ‘stick’ where you want it to, the position will be absolute relative to the column and will overlay with the button, that you can leave untouched.
Beware though that if the button is raised it will always be in front of the label, other wise you can use ZIndex to decide which one stays on top of the other in case you willwant to use this for future apps or situations
