Custom attribute from front matter for side menu title

[mnlbox]

Feature Description Hi,

I would like to use .Date variable of page for side menu text value. As I checked title.html partial it seems you are using filename value as fallback. How can I change this behaviour and overwrite this partial without forking Hextra? https://github.com/imfing/hextra/blob/7b7eb0f1f32c401d5f76337b32af4996cfc67d94/layouts/partials/utils/title.html#L16

Sorry if it's simple, I'm new in Hugo.
