Set default library for save-dialog

[Mike]

Hello

I have a form template connected to a content-type. I'd like to use this
form in several doc-libs. When opening a new form with the forms-service the
form is save directly in the connected doc-lib. If the user opens the form in
Infopath the doc-lib has to be selected each time.

I thought of using the submit button, but since the form is use in various
doc-lib that doesn't seem to be an option.

Does anyone know of a solution to this problem. Thanks for your help. Kind
regards

Mike
