You can ask them to transfer the documents from your previous evaluation to the new one. That's what I did. But, the problem is, since my Bachelor's degree was from India, they wanted me to ask my university to send it again due to that new rule, but told them that I am no longer in that country and it wouldn't be possible. So they sent the documents to my university directly to get them verified. Luckily, after a month's time my university sent the confirmation to WES yesterday and now the new evaluation is in progress.
