multi-language event builder

Hi,
I’m using the plugin in a multi-language site with polylang.
The calendar works fine, but I haven’t founsd a way to translate strings inside the events builder.
Is it possible to use php or custom shortcodes inside the vent builder?.
I’d like to do something like this:

[link newwindow="true"]<?php pll_e('More details...'); ?>[/link]
