Thanks for your work on this! That is very nice and works like a charm.

I would love to tweak it a little bit to remove some of the duplication in the code, if you don't
mind I will do that and ask you for review again.

Setting this to approve as it fixes the issue nicely, I put up a additional MP that tweaks it slighly.
