I don't have a concrete idea of how to realize this yet.

Perhaps a template engine like Handlebars could operate at render time?
However, there is a clear need from users. This might also involve breaking changes, so it might be included in V4 depending on circumstances.

• ref: Dynamic text with unknown length should add new pages accordingly while generating the PDF #437
• ref: Multi-variable Text Plugin #388
• ref: Custom Schema Plugin #208 (comment)

Describe the solution you'd like

• Addding preprocessing and custom plugins for PDF generation.
• Adding page break processing when text overflows.

Describe alternatives you've considered

Add a process to replace placeholders before calling the generate function.
