AcuXDBC, create System catalog

I have got following Situation. If you want to create System catalog entries you should write

xfilename#tablename#filename 

AcuXDBC user's guide says at page 5-15. It means

xfilename                Name of XFD file
tablename               Name of database table use via AcuXDBC
filename                  Name of physical VISION file

Now, I have got any VISION files with equal XFD-structure and I want to join them to one table. Following example:

#xyz.xfd#xyz_table#xyz_file_1
#xyz.xfd#xyz_table#xyz_file_2
#xyz.xfd#xyz_table#xyz_file_3

More than one physical VISION files should be join to one AcuXDBC table. All data are supported by one table.

Is it a way to do this?
