How to translate elements within the theme?

Hello everyone...
I was able to translate some menu topics using:

Code:

<variables>
   <subset.colorset>Cores do tema</subset.colorset>
   <subset.background>Plano de fundo</subset.background>
   <subset.Sounds>Lista de músicas</subset.Sounds>
   <subset.iconset>Tema dos botões</subset.iconset>
   <subset.systemview>Rotação dos sistemas</subset.systemview>
 </variables>


Is there a way to translate the value of "systeminfo" (which displays system item numbers)?

*It is actually already translated in the latest version of Retrobat, but now there is a new option to create "Collections".
When “systeminfo” reports the number of collections on the main screen, it is not in PT-BR.

Exemple:
As it should be: "1 Coleção" (singular form)
"7 Coleções" (plural form)

As it is at the moment:
"1 collection" (singular form)

"7 collections" (plural form)

*Thank you all!
