Is there any update to this? I'd really like to customize this in the printed invoice if possible.

Currently I have to delete all of the time entries with links (keeping the links to the invoice) and copy/paste the information into a new unlinked line item to make it work properly.

The UI is very confusing. There should be an indication that there will be a different format in the final invoice. I missed that the first time and had a client reject an invoice. Also I intentionally log time to the nearest 6 minutes to get my decimals to line up correctly, so I'd really be ok with a global setting.
