Using webflow forms with something like 'formtools.org'

Is there any way to ‘disable’ the webflow form handler and instead use an external form handler (separate server)?
I would like to be able to add upload a file to a form and I need a way to do it that doesn’t cost extra.

I have a server ready to do whatever is needed.
this is the code i need to get into webflow, but i don’t need ‘two’ replies going to a client.

<form action="http://www.MYWEBSITE.com/formtools/process.php" method="post" enctype="multipart/form-data">
<input type="hidden" name="form_tools_initialize_form" value="1" />
<input type="hidden" name="form_tools_form_id" value="1" />

OH I guess I need to ask if I can somehow ‘create’ an upload field/input as well in webflow.

Probably not to all of this.
Man PLEASE add this feature asap it is becoming a real issue with clients.
