TextMesh/3DText modify shape

I noticed that when you add a 3D Text object to your scene it has two components: Mesh Renderer and Text Mesh; I wanted to modify the mesh so that it's a curved text, but it seems that there is no option to edit the mesh. (It's usually done from the MeshFilter component, but you cant use MeshFilter and TextMesh at the same time). It is possible to edit the shape of the TextMesh?

Thanks :)
