Approvals Process - One Click generate comparison to previous finalised revision

We need to find a better way to review the changes which have occurred for the approver to get context. We need to streamline the way which compare the previous finalised revision to the current working approval revision.

Currently the user must click into the location, click compare, Click a previous revision, Click the last revision, then click start comparison.

This flow is a bit longwinded for the approver.

I think the best approach would be to introduce a field in the approval screen along the lines of "compare to last finalised state" which will take them straight into the generation of "start comparison", ie. the one click from approval screen will show them the comparison results to previous revision once it is generated.

This will be the case for 99% of approvers, wanting to compare to the last finalised structure. If the approver wants to compare to a previous revision, or different location - they can go through the current approach.
