Change Stock Status values?

Hi,
i have a question about skroutz feed xml
i have set in caption availability the field name Stock Status that way when a product is available or not i have InStock or OutOfStock in my xml

so when i export the xml now it says
<availability>InStock</availability> or
<availability>OutOfStock</availability>

how can i change the words InStock and OutOfStock to my greek language?
so that way says
<availability>Άμεση παραλαβή/Παράδοση 1 έως 3 ημέρες</availability> or
<availability>Εξαντλήθηκε</availability>

this is something that skroutz service ask me to do it and actually they want to do it exactly with these greek words-phrases!

thanks!

Plugin has feature. It can change values. Check if your skroutz.xml has ConvertValues block.
Change the NewValue parameter.
