In general, no. However if Maxima is asking about the sign of a symbol
(as opposed to a more general expression) then you can set a default
response via assume_pos and assume_pos_pred.
After asking a question, Maxima returns just one result.
I think it would be more useful to compute a result for each alternative
and return something like: if a > 0 then result1 elseif a < 0 then result2 ...
I have made an attempt to implement such a scheme -- I'll post
more about that later.
By the way, what is the integral in question?
