How to include Array in Quartus 11.1 Block Diagram

Hi,

I work on a VHDL-Project in Quartus 11.1 that has a Block-Diagram as Top-Level. I use the Block-Diagramm for a Project-Overview and to connect the different VHDL files.

Now, my problem is, that I would like to define an two-dimensional Array as a Block In- or Output. I know, how I must define a Vector, but not how to define an Array in a Block-Diagram. If the top-level was written in VHDL, I had not that problem. But I would use the Block-Diagram as top-level.

Can anybody tell me how I must define an two-dimensional Array as a Block In- or Output ?

regards
