  We present a protocol for designing appropriately extended $\pi$ pulses that
achieves tunable, thus selective, electron-nuclear spin interactions with
low-driving radiation power. Our method is general since it can be applied to
different quantum sensor devices such as nitrogen vacancy centers or silicon
vacancy centers. Furthermore, it can be directly incorporated in commonly used
stroboscopic dynamical decoupling techniques to achieve enhanced nuclear
selectivity and control, which demonstrates its flexibility.
