Altium, Copy Net lables and increment values by set number?

[mrpea]

I often have to update schematics in Altium and one feature i have not been able to find is to bulk update a copied set of Net labels and increment the numbers in those labels by a number other then 1.

For instance i have 32 Netlabels (MS4-1 to MS4-32) and i want to create a copy and update quickly to (MS4-33 to MS4-64)
i cant seem to get to the correct formula in Altium smart edit.

Thanks.
