Добавить текст на стрелку в блок-схеме

Дополнительный вопросРисование стрелок из разных краев узла/блока решений

Проблема, с которой я столкнулся, кажется довольно простой, но я не смог найти решение в архивах или где-либо еще. Вывод моего .texфайла — это блок-схема ниже:

Блок-схема

Я хочу добавить текст «Нет» на вертикальной линии, выходящей из самого нижнего поля решения слева (с текстом «Проверка перегрузки линии»). Его также можно разместить на горизонтальной линии так, чтобы он находился прямо под «Да».

Я добавил текст "{No}" в нескольких местах, но все они приводят к ошибкам компиляции. Может кто-нибудь показать мне правильный способ заставить это работать?
