EPM10 - Select multimembers on selection

Hi Experts,

we have recently migrated to EPM 10 from BPC 7.5 and we had a scenario where in the user had an option to select the members from the list box.

In EPM 10 is there any function like EPMCONTEXTMEMBER or EPMOLAPMEMBERO     which would allow the user to choose from the list shown below.

Business group is maintained on Page Axis and we wanted to have only few members under HR group for selection.

Ex: say a member under HR1 and two members under HR3 and HR4 and 4 members under HR5   

OLD report bpc 7.5

EPM 10 >>>>>>>>>>>> Can we achieve similar selection in EPM 10(only select few members under HR1 and so on)

Thanks,

SSK
