can I still modify the completed answer before I submit it

Every proposed answer can be customized until confirmation

Yes, every answer that the system retrieves from the chain file remains a proposal until you click "yes". As long as you have not confirmed, you can modify the text, supplement it or replace the associated evidence. That applies to every field, whether it concerns the company's registration number or a substantive question about your ISO 27001 measures from Annex A. Only after your confirmation does the answer go to your customer's portal.

This is relevant for lists where one question is formulated slightly differently than in the chain file. Think of a NIS2 questionnaire that asks for "access control" while your file has recorded the measure under a different name from article 21(2) — substantively the same, but the customer may want to see the terminology of his own format back. You then adjust the wording without the underlying fact changing. If the fact itself changes — for example because the number of employees has been modified since the last update — then you update that in the chain file itself, so that future lists also show the correct figure.

Confirmation per answer follows from the "yes/no" mechanism

We build the answer side, not the assessment side: the system proposes an answer based on what is in the file, but submits nothing without your consent. That confirmation per answer — yes or no — is the mechanism that makes adjustment before submission possible. No separate "edit" step is needed; saying no to a proposal is already the first step of adjusting, after which you open the field for your own text or attachment. Note: what you modify here modifies the answer in your own submission. If you want a modification to also apply to future lists, then you adjust the source in the chain file — not just the one answer on the screen.
