It is now possible to add, edit and remove custom buttons that can be shown on the button bars. The "Add or Edit Custon Buttons" option can be found on the "Maintenance Options" within "Reports & Parameters".

Alternatively you can create a custom button from the location within Platinum where you want the button to appear. From the location, press "F12" to pop up the "Functions Available" screen. From there, press the new "Custom" button to pop up the "Custon Buttons Properties" and from there select the function you would like the custom button for.

You are now also prompted to create a custom button whenever you record a new macro.
