I would like to change the definition of `\f` to something like this
```tex "f" = #(make-music 'AbsoluteDynamicEvent 'text "f" 'tweaks '(((DynamicLineSpanner . horizon-padding) . 0.1))) { \stemDown f'4\f f'4\p } ``` to handle issue #4159. However, if I do the above the `horizon-padding` property can no longer be overridden with `\tweak` or `\override`. How can I fix that? In other words, I would like to set the `horizon-padding` property for `\f` as if I provided a default value for the `DynamicLineSpanner` grob in `define-grobs.scm`. Werner
