Example: Document automated with multiple optional paragraph. Don't know
how many paragraphs are going to be inserted or which will be the last
paragraph. The last paragraph needs to be kept with the next paragraph, but
the previous paragraphs do not need to be kept with it.

Setting all the optional paragraphs to "Keep with next" won't work because
Word will ignore it if it is more than one page (Word cannot keep multiple
pages of text on one page). However, if the next paragraph after the last
optional paragraph were set to "Keep with previous," then it would work.

Example:

This is an optional paragraph that does NOT need to be (and should not be)
kept with the next optional paragaraph.

This is another optional paragraph that does NOT need to be (and should not
be) kept with the next optional paragaraph.

This is yet another optional paragraph that does NOT need to be (and should
not be) kept with the next optional paragaraph.

This is NOT an optional paragraph that follows the last optional paragraph
before it (we don't know which of the above paragraphs will be the last
optional paragraph) and that should stay with the paragraph before it. "Keep
with previous" would allow for this.
