  High-$p_T$ jets are an important tool for characterizing the quark-gluon
plasma (QGP) created in heavy-ion collisions. However, a precise understanding
of the jet-medium interaction is still lacking, and the development of more
sophisticated observables is needed. This work presents a tool that allows for
the exploration of alternative high-$p_T$ observables in a variety of collision
systems. The tool builds on the publicly available JEWEL Monte Carlo code, and
allows for the evolution of a jet on any given (2+1)-dimensional background.
Proof-of-concept observables are also presented, studied using the latest
version of JEWEL, JEWEL-2.4.0. The simplicity of the separation of the physics
of the jet from the physics of the medium (while still allowing for the usual
JEWEL medium-response), allows for easy interpretation without the need for
complex parameterization. Results are produced using the RIVET toolkit, which
allows for transparent preservation and development of analyses that are
compatible with experimental methods. The code and analysis used to produce the
plots presented here are made publicly available on a Github repository, with
up-to-date usage instructions. This tool is expected to be useful to the broad
jet-physics community for the study of precision observables for jets.
