Panchromatic band

Is there a way to process the panchromatic band separately? When I disable some bands of images (keeping only the panchromatic enabled), the software gives me an error:
“Error e0204a: Too many missing images leading to incomplete captures.”
And I’m not able to get the panchromatic reflectance mosaic at its higher resolution.

Or does Pix4D perform pansharpening automatically? Because all of the band reflectance outputs have the same resolution, which is not quite the resolution set for the flight (4cm), but is not much lower (6 cm).
