Time-varying effects and long-format datasets

[ocolluphid]

If we have a dataset in long-format (see "time-dependent variables" under this lifelines post: https://lifelines.readthedocs.io/en/latest/Time%20varying%20survival%20regression.html) will scikit-surv allow for time-varying variables in Cox and other models? If not, does this mean that we must collapse each row to just one ID and sacrifice the time-dependent variation?
