Number of decimals in "Default prices" column in Customer List view


When I view my Customer List, there is a column for "Default prices". It currently shows 4 decimals, which is making it rather difficult to recognize rates at a glance. Is there a setting where I can change it to show only as many decimals as necessary? I.e. if my hourly rate is 40 EUR, it would show only 40, no decimals, and if my per word rate is 0.12 EUR, it would show only 0.12 and not (as currently) 40.0000 and 0.1200, respectively?
