Change new wirless network to "on demand", instead of "automatic"

Hello,

When a user connects to a new wireless network (using windows wireless
services)  ,the default setting is "automatic" connection.

Is there a way to change settings ,that When a user connects to a new
wireless network ,the default setting would be "on demand"?

Thank you,
