Yes, and damped oscillatory magnetic field test are described in IEC 61000-4-10 although I don't have the latest edition of EN 61000-4-10 and don't know whether 10 MHz test method is included in the standard. However, if it is not included yet or if it is included and the generator specification doesn't contradict with that of IEC 61000-4-18 generator, I think it is possible to generate the required magnetic field using IEC 61000-4-18 generator and the test method described in IEC 61000-4-10. At least for slow damped oscillatory magnetic field, some manufactures offer their IEC 61000-4-18 test generator as the current source, I think.
