Add pms_get_subscription_plan filter

Hello. Thanks for great plugin! I am trying to localize subscription plan names. I use Polylang (pll_register_string) and I need the way to hook a subscription plan retreiving. I found a filter “pms_get_subscription_plans”, but unfortunately “pms_get_subscription_plan” hook is absent. Could you add filter hook? Something like:

    function pms_get_subscription_plan( $id_or_post ) {
        $subscription_plan = new PMS_Subscription_Plan( $id_or_post );
        return apply_filters( 'pms_get_subscription_plan', $subscription_plan, $id_or_post );
    }
