Form submit behavior

Hi,
If I create a form, Blocs2 create a php file in includes/form_ID.php that send an email with form data.
Can I edit this formID.php in blocs2 to use my custom script?

Now, I delete Blocs2 php and upload my php, but if I can integrate my php in blocs, I can upload all folder in FTP without any other operation.

Thanks!

Anyway, if I can assign a value every form field like this:

will be perfect!
Thanks

sorry:
< input name = “field” required = “required” type = “radio” value = “2” / >
