So use a custom flowable then... ?  Does a flowable know how much
space it needs before its drawn or do I just have to know the size of
the text contained in the custom pinned flowable?  Just trying to wrap
my head around how to figure out how to determine how much space the
flowable needs to use up to get itself to the bottom and still leave
enough room to contain the summary contents.

Thanks,

Eric
