Gmf editing and/ or titleblocks

Hi, has anyone discovered a way to edit the gmf code within capella in order to adjust some of the ways capella displays its diagrams.

The aim is to attempt to create a titleblock with the formatting locked for use across multiple diagrams rather than having to reformat and create new titleblocks everytime a new model diagram is made. If there are any other ideas for how to do this (maybe a way to use capella studio to create a specific element with a set size and text/ image input) then please respond!

The interest in editing the gmf code is to see if there’s a way to achieve this goal by making some adjustments to the way titleblocks work.

Any advice welcome!

Many thanks,
