I've been looking at this today and it's actually pretty easy to add this functionality.
Normally I don't like to add enhancements this close to release, but this is easy to turn on/off with an option and the code is isolated, so... on Monday's beta and in version 17.0 (due out at the end of October), you'll be able to search any column like this:
The current behavior is to only locate rows in which all specified columns match the search value. There was actually a bug in there (invalid variant operation) on repeated searches, which has been fixed.
And this is even easier...put it on "FIlter Data". Select all columns and just type what you want to search for.
