Can I annotate a PDF with gImageReader to make it searchable?

Question

I am using the latest version of gImageMaker (3-2023, Windows 10). OCR works fine.

I use a PDF as source, which is not searchable and just want to add the OCR text to the PDF so it becomes searchable.

So far I have only been able to create a new PDF with the text. But I want to keep the original PDF, just annotated with the OCR text.

Any chance to do that with gImageMaker?
