KiKit Text Variables to work also for paths and filenames

[thisisgregm]

Prerequisites

• I have read the documentation and the proposed feature is not implemented.

Description

I'm on Win 11 + KiCad 9.0.5 + KiKit 1.7.2.

I've just tried to use KiKit text variables for path and filenames generated, so example:
kikit panelize --preset Outputs/kikit-panelization-settings-custom.json Projectname.kicad_pcb Outputs/{boardRevision}-{date}-panel.kicad_pcb

From the example above the variables boardRevision, date, etc are not converted to their values.
Works fine for text on the panel itself.

Would it be possible to implement the text variables for paths and filenames?

Many thanks.
