Aye, this one begs the "Why" part. There are ways to do that, but they really don't gain you a lot. One place that I do something like that a lot, is taking a DINT status word from a device, and breaking it down to named bools, but I do that with UDT's*, and it is just a simply COP there.
*Okay, not actually "Simply", you need to externally edit the UDT to give names to the individual bits, but workable.
