Display Units not corresponding with currency

Hello,

I've come across a situation where I've chosen SEK (Swedish kronor) as currency but the callout value on both the normal Gauge and the Tachometer is in English format when the value exceeds 1 000 000 000.

Where I expect a value saying 1,225 mdkr (or something similar for "miljarder" which is billions in Swedish) it instead reads as 1,225 bnkr (billion kronor).

Is there anyway to solve the above issue? Is it possible to add your own, custom, unit?

Thank you in advance!

Cheers,

Anders
