Hello jorenlogo,

first of all welcome to the forum.

Of course, you can query an input multiple times, regardless of whether it is physical or network-enabled. However, you can only place the block for this once in the diagram.

Yes, if you position the block at the beginning of the diagram and want to query again at the end of the diagram, this can only be done via the "long line".
But you can separate them with the "Separate" function.
You can rejoin separated lines with the "Join" function.

Check out the attached video.
