When I search for flights home (Boston) from Santa Clara, I usually do a search for "SFO,SJC" to "BOS". This shows me all flights from SFO and SJC to BOS allowing me to pick and choose which flights work for me (time wise) as well as what makes the most sense price wise.
As for the multi-dates, when you select a date, you can click the "+/-" buttons to add time to your query. You can also manually add "+-n" to your date to give a range.
So, say I was open to flying out July 12, 13 (original), or 14 - I could update my date to look like: "Jul 13 -+1"
