Thank you for the reply! I can do it already using regex (or the Excel plugin I linked to which I would encourage you to install and test it, it could give you further ideas). My point was with a focus of improving this great piece of software.
I can see right next to it in Pivot Table there is a number of settings. And it is strange to have a full icon for just a simple (and rare) action without any settings.

The simple functionality could be maintained without causing confusion in the user. For example, he would have to select a full column for the options to appear.
