It's mostly possible by adding something like this to your post-processing script:
{REPLACE "; feature bridge" "SET_VELOCITY_LIMIT ACCEL=1250\n; feature bridge"}
{REPLACE "; feature skirt" "SET_VELOCITY_LIMIT ACCEL=1000\n; feature skirt"}
{REPLACE "; feature infill" "SET_VELOCITY_LIMIT ACCEL=2500\n; feature infill"}
{REPLACE "; feature dense infill" "SET_VELOCITY_LIMIT ACCEL=2500\n; feature dense infill"}S
{REPLACE "; feature support" "SET_VELOCITY_LIMIT ACCEL=2500\n; feature support"}
{REPLACE "; feature dense support" "SET_VELOCITY_LIMIT ACCEL=2500\n; feature dense support"}
{REPLACE "; feature gap fill" "SET_VELOCITY_LIMIT ACCEL=2500\n; feature gap fill"}
{REPLACE "; feature solid layer" "SET_VELOCITY_LIMIT ACCEL=1500\n; feature solid layer"}
{REPLACE "; feature inner perimeter" "SET_VELOCITY_LIMIT ACCEL=2500\n; feature inner perimeter"}
{REPLACE "; feature internal single extrusion" "SET_VELOCITY_LIMIT ACCEL=3000\n; feature internal single extrusion"}
{REPLACE "; feature outer perimeter" "SET_VELOCITY_LIMIT ACCEL=1800\n; feature outer perimeter"}
{REPLACE "; feature external single extrusion" "SET_VELOCITY_LIMIT ACCEL=1800\n; external single extrusion"}
{REPLACE "; feature prime pillar" "SET_VELOCITY_LIMIT ACCEL=1800 \n; feature prime pillar"}
