Hi,
Yes, you can definitely use native Ibex controllers within the PennController.Template command, as described in the documentation (second example—you don’t have to have two screens, you can use just one “Acceptability” controller instead).
Though to be fair, you can have boxes with PennController scales as well, using .settings.button. And I just realize now that I haven’t added the documentation page for this option, which I’m gonna fix ASAP.
You would probably want to play with the CSS though, as the default rendering is quite ugly. You can take a look at the Aesthetics documentation page to get a sense of how CSS works in PennController.
Let me know if you need assistance with either of these two solutions.
