Full with based on parent group/artboard

Feature request / enhancement

For paddy it would be really nice if we can have the option to have a 100% width based on its parent container (which is typically a group or artboard)

This means that if i have a button, i can choose weather i want to apply a padding of 24 - or if i want to have a button which is full width on mobile minus the padding of the parent group
