I am working with multiple quotes within a single opportunity. As a quote is
revised and replaced by a new quote, a quote rule automatically schedules a
task to follow-up the quote.

This task appears in the history for the quote (once the task has been
completed obviously), but it does not appear in the history for the
opportunity. The quote is related to the opportunity as it appears in the
quotes tab for that opportunity.

I expected to see the history item in the opportunity history if I included
'Related Records' in the filter - but it's not there. Am I missing something?
