Is it possible to create a variable size subVi (extensible)?

[MrX_G]

I was wondering if it is possible to create a subVi where its size (and imputs/outputs) can be extended. To be clear, something like the concatenate funcion, where you can change its size by making it bigger.

That doesn't allow the drag to add more inputs, it just changes which inputs/outputs are visible. I think OP wants a subVI with an increasable size of inputs/outputs similar to Index Array or Concatenate Strings.

Good point, my suggestion really only offers a cosmetic change in the way your block diagram appears. OP, you could maybe look into XNodes to do what you are describing, although it will probably take some work. Last I heard they are a "use at your own risk" type of feature that is not officially documented or supported.

There is some info here to get you started:

All true, and while fun they are often way more trouble than they are worth.  Usually there is a pretty simple workaround that just uses a bit more code than you originally wanted.

And, as always, a relevant XKCD.

Indeed there is, I will just stack single SubVi's, but I wanted it to be more space-efficient, just a matter of looks since others have to understand my code.

Seems it is the only way to achieve it, I will mark it as a good answer. Thank you.

Not really, no, the general solution to such scalability is arrays. Assuming you have a scalar or cluster input, place it in a wrapper and use an array of said cluster and loop through it.
