Lightroom for mobile: View image file size (in megabytes)

Is there any way to view the size of the image file on Lightroom Mobile? (iOS in my case) For example, we can view metadata like "2100 x 800 px" but we can't view "7.5 mb". This information would be very helpful when distinguishing which is the better image when removing duplicates on the go. 

If there is no way to do this on the mobile app (it is possible on the desktop version), then has anyone seen a request for this simple feature? I can't seem to find any information about this.

Thank you very much!
