Add spheres based on x, y, and z coordinates and radius from txt file

I have a list of spheres in a text file that has the format of x, y, z, and radius. Is there an easy way have COMSOL add these spheres to the geometry? The only module beyond the base product that I have is the RF Module. An example of my sphere coordinate/radius file would look something like:

10    20    5    4
13.6    18.2    5    6.1

42    23    5    3.1
