VIs have fixed number of inputs, and as you mentioned, they allow for
unlimited amounts of data through arrays. If you want a growable node
like build array, there are a couple options. In LV7 and above, there
is a subVI style that is bigger, with the blue border, and it allows for
textual terminals at the bottom. These are much bigger, and it is more
obvious what someone is wiring to, but they also take more space, and
I'm not sure they are what you want, but probably worth looking at.
Second option is to really use a build array. You can either teach your
users to put a build array in front of the subVI and build an array, or
you can build a merge VI.
A merge VI is how the 3D graph and the polar plot drop with subVIs
already wired to other objects. It is a regular VI whose item in the
palettes has the Merge Option turned on. In this case, instead of the
subVI being dropped, its contents are merged into the user's diagram.
You could build your subVI using arrays, then build a merge subVI for
the palettes. In the merge VI, place a build array with whatever you
want as the default size. Then add the merge VI to the palettes and set
the option. When dropped, you will get the build array's default size
already wired to the other subVI.
