Lumix GX7 - Is it Possible to Display Saturated Areas Whilst Composing?

I'm just learning how to use my new GX7. The camera has two features to assist preventing overexposure in the highlights:

1. Histogram display
2. Display white saturated areas in Auto Review (manual p 79)

I find the second feature more useful but the highlighting is only displayed after taking the photo.

Is there a way of displaying the white saturated areas whilst composing a photo? I have an Olympus C-5060W camera from 2003 which displays both over exposed and under exposed regions whilst composing.
