When updating a block or swapping with an updated one or a different block, It would be very helpful to be able to select "Just update pins" leaving descriptions the same. When swapping PLC Static block, which are essentially similar having the same number of inputs/outputs, but the pin numbers & pin descriptions are totally different, I would just want to update those not the I/O descriptions. Think switching between PLC's that have AC or DC I/O. Also, if there are corrections to the block because of errors, it is necessary to swap & overwrite all to get pin numbers to update. We spend an inordinate amount of time messing around because of this..
