I think so.  I made good progress this evening.

DLMF 10.32 are all indefinite integrals.  For example 10.32.1 is 
integrate(bessel_i(0,z),z)

Maxima already defines this as
integrate(bessel_i(0,z),z)
  = 
(1/2)*z*(bessel_i(0,z)*(%pi*struve_l(1,z)+2)-%pi*bessel_i(1,z)*struve_l(0,z))
using http://functions.wolfram.com/Bessel-TypeFunctions/BesselI/21/01/01/

To change this you would need to modify the 'integral property on 
%bessel_i defined in bessel.lisp or redefine the function 
bessel-i-integral-2
