How to group language variants in Google Analytics' Users Flow

Question

In Google Analytics' Users Flow, language variants such as en-us and en-gb are shown as different flows.

As my website&marketing does not differentiate between language variants, how to group variants in order to just have single flows en, fr, etc?

Answer 1

You can customize it by clicking settings ico (next to selected dimension).

Then you see:

This setting can be saved using a browser bookmark, as customization details are in the URL.

Matching "others"

You can't exclude something from a match, but you can add matching regexp rule below.

Interpretation:

1. name 'english' every value from 'language' dimension which contains 'en'
2. name 'french' every value from 'language' dimension (subset without matches from first rule) which contains 'fr'
3. name 'others' every value from 'language' dimension (subset without matches from 1st and 2nd rule) which contains or not any char
