Изменение квадратного поля флажка с квадратного на закругленное с помощью WPF

Я успешно создал закругленный угол для флажка, прямо сейчас у меня проблемы с подключением шаблона элемента управления к другим флажкам. Можно ли как-то подключить шаблон элемента управления к флажку, сгенерированному из серверной части?

первая часть — это шаблон элемента управления, измененный, чтобы изменить квадратную рамку на закругленную рамку

вторая часть - это флажок, сгенерированный из бэкэнда и добавленный во внешний интерфейс.
