Add A Line Below If Cell Is Not Blank

I am trying to stack the values of a chart into a single column.So my data looks like this:

-------A--------B
1 Value1 Value2
2 Value3
3 Value4
4 Value5 Value6
5 Value7

If cell 1B does not = 0 I want to add a line between line 1 and 2 (I'll call that line "11") and take Value2 and paste it into 11A If cell 1B is blank I want it to do nothing

So I want my data to look like this:

---------A
1....Value1
11..Value2
2....Value3
3....Value4
4....Value5
41..Value6
5....Value7

I want to automate this as much as possible but if it's not easy to do I at least want to at least automatically add a blank row below if value does not = 0 and then I can manually move the values as needed.
