The best way is to create a bus Data[1..8] and then a separate signal CLK. Buses on-sheet are cosmetic only, connectivity is established by net labels, but if you go off-sheet and you do not wish to make explicit all the net names in a bus, the bus must be in standard form, which should be obvious, since we have no means of giving a bus a name distinct from the signals within the bus. This would indeed be an improvement. If we could name a bus "CONTROL," for example, and we had a means of defining the signals which are members of that bus, such as RD*, WR*, CLK, etc. -- I don't know right off what that would look like -- then we could have miscellaneous names. But we don't, so we can't use a miscellaneous bus for intersheet connectivity. (You can use a bus for off-sheet connection if you have nets global, because the net labels which you must put on wires coming off the bus will establish connectivity. But if intersheet connectivity is established by Ports or by Ports and Sheet Symbol connections, with net labels only applying to the single sheet on which they reside, you are stuck with numerical sequence bus names only. --i.e., you can have more than one CLK signal, a common situation when a schematic is put together from pieces of old projects.)
