Document owner rights for Expert by default

I recently discovered that when an expert starts documenting a new process, they are not automatically given Document Owner rights to documents they upload. This means that while they are creating this process and it hasn't yet been approved they cannot make any changes to documents they add, and need to completely delete and readd the document. They can't even upload a new version or change the label.

The workaround at the moment is to manually assign document ownership rights to individuals and this must be done at a folder level, however this is cumbersome and lacks logic. It would be better if by default the expert of a process was also the document owner for any documents they add to that process, while it is in the "unpublished" state.
