Can you turn off the recent items search within time and labor on the webclock?

Summary:

Our client is highly integrated with Projects so we are feeding in Projects and Project Tasks into the Oracle Webclock for time entry. When we go to select a Project for the first time a large list of values displays and then the next time I go in to select another project the most recent item I searched for is what displays. This will cause a lot of confusion for users because the only way to get other values to show is by starting to type in another value.

Is there any way to turn this feature off so that the user doesn't see the recent items when they go back to that section?
