Only one decimal place in Rough Cut Planning Profile

Hi all

   When creating rough cut planning profile (MC35), in the resource table, the system in letting me enter units (Hours in my case) only up to one decimal place. To get accurate capacity planning I need to enter units up to 2 decimal places, especially when assigning more than one resource to the same material. Please let me know if there is way to increase the allowed decimals places to 2 decimals either through configuration or custom changes.
