Question: Spherical Coodinate Definitions

Maple defines the spherical coordinates angle phi from the Z-axis to R, and the angle theta from the X-axis to R.  Many texts and literature define the angle phi the opposite way from the X-axis to R and the angle theta from the Z-axis to R.  Therefore, when I input a problem from a text, which defines phi and theta by the second definition given above, I have to remember to swap the values of phi and theta in order to get the correct answer. 

Is there a quick and easy way to make Maple accept spherical coordinates according to the second definition?
