In one of our workflows, we have three possible conditions that could be present

Let's say these are A, B, and C.

The only way I can describe the logic about what is and what could be is to draw from my programming background.

Workflow only lets us set up the logic that it might look like this:

If Condition = A Then
... (A's actions)
Else
... If Condition = B Then
... (B's actions)
...Else
...... If Condition= C Then
......... (C's actions)
...... Else
......... (other conditions)
.......End If
... End If
End If

But if I were to program what it could be using Select Case it could look like

Select Case Condition
Case A
... (A's actions)
Case B
... (B's actions)
Case C
... (C's actions)
Case Else
... (other actions)
End If

The methodology that mimics the Select Case provides more choices.

Everything is If... Else. We'd prefer instead to have something like

I also attached a rudimentary graphic to illustrate.
