EPM Input Form member filtering

Environment: EPM 10 NW, SP 15

I am building an Input Form with Accounts in Row axis and Time in Column Axis.

I have master data with top level account node and 3 levels down. Some of the members have their PROPERTY1 set to Y.

Now, my Input form should show only the accounts with PROPERTY1 set to Y

This is simple in EVDRE as in expansion range we set PROPERTY1=Y  but i am not finding an equivalent in EPM.
