The short answer is no, there is no way to test multiple dates in one go. .
I suggest running a search on Aeroplan.com and just keep clicking next/previous day in the results.
There should be no problems with LAX-CDG in April, but ANA may have a hard time, cannot handle more than 1 connection.
An easy check across the range of dates is the calendar on Continental.com, but beware, only limited partners are shown - ie. no LH or LX
