# Internal: Sets the position of the step if it is `nil`. That means that
# when the step is the first of the process, and no position is set
# manually, it will be set to 0, and when it is not the only one it will be
# set to the last step's position + 1.
#
# Note: This allows manual positioning, but there is a validation that
# forbids two steps from the same proccess to have the same position. Take
# that into account. It would be best if you did not use manual
# positioning.
