Autotext fields for PAS1192 file naming?

The BIM standard PAS1192 has a bunch of codes as part of its filenames and drawing numbering. Codes relate to project phase, location, company, discipline, project ID and drawing or model ID.
It’s been around a while and is gaining traction on BIM projects across the world.

Here’s a short explanation:

Is anyone using this for their sketchup & layout projects? Any tips for making Layout presents the PAS-compliant file name and drawing/sheet numbers?

Our company are implementing this as a standard but I cant work out how to automate it in LayOut 2020.

Cheers
