How to custom day note name created by calendar widget?

[ghost]

When day note is created by clicking calendar widget, note name have the form 'day of month - day of week'. But i want custom the name. 1 way i can think of is using #datePattern={isoDate}, but this will make all the note name is today date, not the correspond day. So, how can i custom day note name created by calendar widget?

I want it to be some code note or a label in root note, not changing the source code of trilium itself.
