Where is the normal and tangent velocities in Shuriken?

In the legacy particle system, one can make a spherical explosion with the particles gradually losing velocity. Adjust the tangent velocities allows you to do t$$anonymous$$s.

I can't seem to find the same feature in the Shuriken particle system. The velocity over lifetime are all using the absolute coordinate system even when changing the space to Local. I'm guessing it's only local to the whole particle system. I'm looking for "local" as in local to the particle itself.

Is t$$anonymous$$s possible? If not, how do I request for the feature?
