How to customise format of HTML program listing export?

[gammalogic]

Is it possible to change the template used when program listings are exported to HTML? I want to include some inline JavaScript and CSS styles as well as add some extra attributes to the tags. Also, the HTML export seems to be outputting as HTML 4 code and it would be helpful to make it HTML5 compliant.

Currently, I can do all this by sending the HTML file to a separate script and modifying the tags, but it would help to know if there's a way to modify Ghidra to do this.
