How to assign names to fixed particle components in an AmrLevel-based particle container?

[Afraid31]

Hi，
I am using a custom particle container based on AmrLevel with fixed-structure SoA/AoS components:
`struct PIdx_Real_SOA {
enum { usx = 0, usy, ufx, ufy, forcex, forcey, nattribs };
};

struct PIdx_Int_AOS {
enum { id = 0, nattribs };
};

class ImmersedBoundaryPoints
: public amrex::AmrParticleContainer<0, PIdx_Int_AOS::nattribs, PIdx_Real_SOA::nattribs>
{ };
The issue is that when I write particle plotfiles withWritePlotFile(), all particle variables appear with generic names such as: real_comp_0, real_comp_1, ..., int_comp_0, ...`
I would like these components to have meaningful names (e.g. "usx", "forcex", "mass") for easier post-processing in ParaView or yt.
Is there a way to assign names to these fixed particle components in the AMR-level particle container？

There is a version of WritePlotFile that takes the component names as an argument: https://github.com/AMReX-Codes/amrex/blob/development/Src/Particle/AMReX_ParticleIO.H#L140

Thank you! That helps a lot.
