Interface 'Ignore Discards' option

In the past, there used to be an option to ignore discards on interfaces -- very useful in Cisco Firewalls.  Anyway... I couldn't find the option so referencing documentation:

https://community.helpsystems.com/knowledge-base/intermapper/training/session-four-training-major-windows/

the option to ignore discards is no longer available.  I have existing maps that have the option turned on on certain devices, but I'm adding new devices and cannot enable this discard option.  How do you enable the option?

To set ignores on interfaces 

Right click on the device then select Interfaces > Window

In the new window there are check boxes for Ignore Errors, Ignore Discards and Ignore Utilization.

If you want to do a mass selection of the ignores for a specific column hold ALT and Left click on a checkbox to select the entire column.
