Expense time entry module do not allow time entry for multiple PC BU'S

Hi ,

Our internal staff need to be able to enter time for projects that are under different PC BU's/GL BU's. e.g one staff is managing both Europe and US implementation project so he would like to enter time against US and Europe project on same time sheet(PC and GL BU's are different for both BU's.

Is this possible with expense time entry module? PC BU prompt on time sheet page is filtered based on GL BU on expense employee profile definition so users are unable to select PC BU that are not tied to GL BU on their expense profile.
