Appointments+ & WPML - cross language appointments


I want to use the Appointments+ plugin on a multilanguage website powered by WPML.
I was wondering if it's possible with Appointments+ to have a cross-language booking system: for instance if I have like an Appointment with max. 10 clients, if 6 clients subscribe using the English version of the website, only 4 places are left, even for the other languages...
Is this possible with the plugin?
