Hi Fabian,
Yes there is a way to do that and it involves more steps and editing in Code View:
Step 1 - you need to find out the IDs for the Studio Account, Advertiser, Campaign and Creative that you want to publish the new file to.
The studio account info can be found in the meta tag in the authoring file of the creative if you download it from Studio:


Step 2 - copy the <meta> tag and paste it in your new DoubleClick file in GWD (Code View), for example:
<head>
<meta name="gwd:studio-creative-association" content="acct=22434861;adv=32272814;camp=37972455;cr=40330009;">
.....
<head>
Step 3 - continue adding the content in Design view. When you click Publish to Studio button, the Studio association info should show up in the dialog. (Please note that when you do this, the previous published file will be overwritten by the new file.)
Let me know if you have any questions.
Thanks,
Emily
