Multi-step document generation, is it possible?

Hi all,

is it possible to generate documents in a multi-step process with relatorio?

I would like to fill a template with relatorio with data and be able to provide the resulting document to a supervisor.

The supervisor should then be able to “sign” the document. In this case, relatorio should input - in a second pass - an image of a signature at a predetermined position in the document.

Best regards,
Dominik

I guess it would make more sense to validate the data in Tryton and generate only once the document when the data has been validated.
