Is there a setting that will allow the decimals to be shown for durations?

Using 3.2 EPPM

I'm loading resource man hours for crews for activities. The man hours were computed from a spreadsheet and most of the durations have fractions to get the correct total man hours. The crew size is 48 hours per day (6 workers for 8 hours). To get the correct number of hours for an activity that needs 410 hour total, I enter a duration of 8.54 days, and I get 410 hours. The program shows 9 days, but the 8.54 is working. I know this because 9 time 48 is 432. Is there a setting that will allow the decimals to be shown for the durations?

Thanks,
