They did. The original plan involved 3 docked Progress capsules to make
coordinated burns, along with the thrusters aboard the ISS itself.

Russia isn't that cooperative anymore.

Its non-trivial, since the goal is to get it to enter with as short

Getting enough delta-v to do so quickly enough is complex.

Here's Scott Manley, two years ago, discussing the original plan.
