Create an editing form in FrameMaker

Use-Case:

An editor would like to use a form while proof-reading a manuscript. The form should contain a few drop down lists to pick from and a free form text where the editor can then add a comment.

Ideally, this data could be saved inside a marker.

A collaborator could then search on these markers, open the form to read the editor's instructions and then update the comment field.

I've got no issues coding in Frame maker. I need a nudge, a pointer to get me going.

If this solution already exists, then even better

Thanks.
