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?

hextra/layouts/partials/utils/title.html

Line 16 in 7b7eb0f

{{ $title = .File.BaseFileName | humanize | title }}

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