Jobset: Ability to select the export paths using text variables

Description

I would like to have a similar flexibility as the Altium-style output selector for selecting the export paths. This means that the job set files are universal and can be reused without further adjustments and can also be stored directly in the project templates.

For example:

Exports	Export paths
Gerber	Gerber/${PROJECTNAME}_v${REVISION}
Drill	Gerber/${PROJECTNAME}_v${REVISION}
DRC Report	Gerber/${PROJECTNAME}_v${REVISION}_DRC.rpt
Assembly diagram	Assembly/${PROJECTNAME}_v${REVISION}_Assembly.pdf
Schematic	Assembly/${PROJECTNAME}_v${REVISION}.pdf
3D model	Assembly/${PROJECTNAME}_v${REVISION}.step
