Preserve the draft-date?

Hi!

I’ve made a site where the visitors themselves can upload content without having to register on wordpress. This is via a plugin where the visitors fill out a form which then is sent directly as a draft which I then approve and publish.

The problem is, when I publish the draft on my site the date is changed to when I published it instead of when it was uploaded and saved as a draft.

Is this changeable? I wouldn’t want to change the date manually every single time. Is there perhaps a plugin out there which can help out? I have searched all around, but haven’t found anything.

Please help! 🙂

Best regards,
Daniel
