Missing i18n function for rules link in views - rewrite link text

I am using rules link in a view with in rules link settings a custom text.
I cannot find a translation option for that text. I searched it in i18n rules link, but there are only the 'default' rules link text strings, not the views costum text.
I did not find a translation field in i18n views either.

How can I translate the custom link text in views?
