I'd probably need a little more info about your scene, but the Widgets kind of already work like radio buttons (more accurately a combobox). But what I did was create a combobox for the end angle of my timer cylinder. So that No matter the widget, you can easily change the angle.
So you just have to match the widget timer length to the timer length of the reset value.
I don't know if this is exactly what youre looking for, but I'm happy to help.
