Connecting bus widths smaller than the port size

If you go to help "How to work with connectors" I think it shows that you can split out individual bits connect them in any order to any bits of another bus that is merged from its individual bits. It also points out that a bus merged say from left to right then it is split from right to left Another thing, you don't have to actually draw the bus from block to block so if your .bdf gets too cluttered you may want to leave out some lines.
