Вопрос по fieldLabel в админке для доп.полей ms2

Подскажите, может кто сталкивался. Одно и то же поле (добавленное плагином) используется для разных шаблонов товаров. Можно ли изменить в зависимости от шаблона подпись поля в админке? Не инфу по наведению, которая указывается в параметре description, а именно подпись (по умолчанию она берется из лексикона _('ms2_product_'+field)). Возможно ли это без переписывания исходников? С extjs на «Вы», по-этому буду благодарен за любую помощь.
Код плагина:
