See PHI933. Ref T13210. Harbormaster build plans were convereted to EditEngine some time ago (see D15357) but the forms were not made configurable.
I believe this was just to avoid unnecessary complexity, and there's no reason not to allow configuration of these forms. In particular, support for form configuration allows you to set alternate default view/edit policies and add instructions.
PHI933 is a specific request for changing the default policies, and this is a reasonable approach to providing support.
