How to control back url within eformaspx action

Is there a way to control at the webform development level to define where to redirect user after an eformASPX action is submitted?

There is a ViewState[“WFGEN_REPLY_TO”] but it seems like we cannot modify this since it may break how the action is to be completed. I tried adding BACKURL_SUBMIT parameter but it does not seem working

Inside the storagePath there is also a session.xml with ReplyTo but updating the BACKURL_SUBMIT does not do anything either?

Anyway we can simply control, for instance:

I found the node in the session.xml that can achieve that goal
