Is there a way to add the Contact and the Account field to the Activities layout view?

Is there a way to add the Contact and the Account field to the Activities layout view?

Right now columns are:  subject; due date; status; priority; and activity type.

If I could add the associated contact and account field in columns and have it appear also on the mobile version that would help quite a bit.

Thanks in advance!
