visitor to select the Gallery for uploading in Widget

Does anyone know if it is possible in the NexGen Plublic Uploader widget to have the visitor who is uploading their photo to be able to select the Gallery themselves where it needs to go?

at the moment everything goes into a landing page gallery and I have to move it manually.

Need the drop down gallery select between the photo description and the upload button.

Any experience with this idea would be appreciated. I would have thought this is an easy development but maybe I am missing something somewhere.
