I would also like to have this feature for filtering.
I have tried using the optional start and end time parameters to attempt retrieving only promoted tweets that fell between the time range, but found that it still just provided all the promoted tweets.
ex:
twurl -H ads-api.twitter.com “/0/accounts/3451ke/promoted_tweets?start_time=2015-12-02T00%3A00%3A00Z&end_time=2015-12-03T00%3A00%3A00Z”
