Ability to choose input data set for copied and pasted subflows

Galen

I often have to copy a portion of a flow to use in a different section. Having the ability to define my input data would make things more efficient and eliminate some human error.

In the use case I have, I want to copy the portion circled in red and paste it to where the green circle is, but I don't want it to branch off the orange circle, I want it branch off the blue, so if I could define what dataset it is attached to, that would be more efficient.

adding something here would be ideal
