Is it possible to have a report that is editable by people who dont have access to the source sheet?


Within the company I work for we have a source sheet with all our projects in.

We need to be able to enable external (sub contractors) people to sign a report which auto fills information into the source sheet. (check boxes) This is so we have an audit history of them accepting projects. However, we not not want them to be able to see the source sheet with the full set of projects that don't apply to them.

Is this something that is possible, if its not is there an alternative?
