You would need to modify the file yourself in order for this to happen:
Hopefully this will be added very soon.
File: template.php
Line 1217: Modify like this
<!– <legend> //–><?php //_e( ‘Billing Details’, ‘give’ ); ?><!–</legend> //–>
<legend><?php echo apply_filters( ‘give_checkout_billing_details_text’, __( ‘Billing Details’, ‘give’ ) ); ?></legend>
And then you can use the new filter in your functions.php file: give_checkout_billing_details_text
With the User Role plugin make sure the user has manage_options capability.
This is what the plugin look for.

You should find the setting within the drop down menu for Seamless Donation above the Log and Help Options.
Yes…create a normal page and give it any name you like.
In that page where you would type your content…add that shortcode: [dgx-donate]
Then update or publish the page.
