Add support for capturing comments. For each input field (data value) there should be a function for inputting a corresponding comment.

[stale]

Hi! Due to a lack of activity on this issue over time (7.776*10^9 ms and counting, to be precise) it seems to be stale. If there is no further progress on it, it will be closed automatically.

If this is still relevant, maybe there is something you can do to move it forward? For example provide further information in a comment, or supply a PR? Any activity on this issue will keep it open. Thanks! 🤖
