VBA Code to link checkboxes to certain columns

I have three columns E(insufficient QTY) F(Too Slow) and G(Not Listed) They all have checkboxes in them. I need to link E to H F to I G to J

The following code works nicely if there was only 1 column of checkboxes but I don't know how to improve the code to run by checkboxes in a certain column. Right now it just searches the entire sheet for checkboxes and links them to the desired column.

Sub LinkChecks()
'Update 20150310
i = 2
For Each cb In ActiveSheet.CheckBoxes
cb.LinkedCell = Cells(i, "I").Address
i = i + 1
Next cb
End Sub
