Excel - Textbox en mayusculas

Buenas
De que manera puedo hacer para que todos los datos que pongo en los textbox de un formulario, se visualizen en mayuscula, sin necesidad de poner un codigo en cada uno
gracias por la ayuda

Usando la propiedad UCase en el evento Change del TextBox, pero es preciso escribírlo en todos estos.

Saludos,
Fernando.
