Changing GL date on distribution on a held, non-accounted invoice w. needs revalidation status

On my setup I have a hold that prevents invoices from being accounted. Since my approvals is mainly on distribution level I require the user to attempt validation before sending to approvals (if not done the correct distribution table for AME isn't populated).

The hold keeps the invoice from being moved to GL and gives it a "needs revalidation" status.

This way the distribution can be changed by the approver and/or accounting staff before final approval. Once the invoice is workflow approved the hold is released, the invoice validated and then finaly it is accounted.

One common request is to change GL dates. For example: an invoice for rent in December might arrive in January, and we want to have the cost on the correct year/month. However, the only way we can do that is by reversing the distribution and entering a new distribution with the new GL date. Since there hasn't been any transaction so far to GL we find this cumbersone.
