OMF and Physical Standby

In normal Data Guard configuration on primary and standby database I want use the same parameters, especially storage parameters eg "db_create_file_dest". This parameter determines default location
Oracle-managed datafiles.

Sometimes I need create tablespace with manually setting datafile name (diffrent directory) and if on standby database OMF is enabled then datafile is created in different directory than on primary - standby use  "db_create_file_dest" location and after that we have to disable recovery mode on standby and move datafile on OS level and rename datafile on standby.
But if before creating tablespace on primary I set  

alter system set db_create_file_dest="" scope=both;

then on standby, database create datafile in the same directory as on primary database.
