On a prototype I have designed, you can be navigated to a certain screen from either one of two different screens. If you selected the button what condition do I have to create so the prototypes understands the screen it originally came from.
E.g. You can be navigated to the 'Renew your Home Insurance' screen from either the 'Welcome' screen or the 'My Home Account'. If I select the button on the 'Renew your Home Insurance' screen how does the prototype know what screen it has come from.
Hope this makes sense.
