Can you run a script from your action?
You can save your settings there:
var traceobj = selection[0].trace();
var opt = traceobj.tracing.tracingOptions;
opt.cornerAngle = 90;
opt.fills = true;
opt.ignoreWhite = false;
opt.maxColors = 32;
opt.maxStrokeWeight = 0;
opt.minArea = 5;
opt.minStrokeLength = 3;
opt.outputToSwatches = true;
opt.palette = '';
opt.pathFitting = true;
opt.preprocessBlur = 0;
opt.strokes = false;
opt.tracingMode = TracingModeType.TRACINGMODECOLOR
traceobj.tracing.tracingOptions = opt;
if not I seem to remember this is doable through Bridge, search the forum I probably saw it here.
