'Drift Over Time' but with easy-ease?

I'm using the nifty Adobe Drift Over Time preset. But its movement is linear. Any way to add an easy-ease to the start of it?

This is applied to the position property of the Transform plug-in:

driftDirection = degreesToRadians(effect("Drift Over Time")("Direction") - 90);
x_offset = Math.cos(driftDirection);
y_offset = Math.sin(driftDirection);
driftSpeed = effect("Drift Over Time")("Speed (pixels/second)");
[x_offset,y_offset] * driftSpeed * (time-inPoint)

Well, with a conditional statement that separates the time for the ease from the rest:

driftDirection = degreesToRadians(effect("Drift Over Time")("Direction") - 90);
x_offset = Math.cos(driftDirection);
y_offset = Math.sin(driftDirection);
driftSpeed = effect("Drift Over Time")("Speed (pixels/second)");
easeTime=2;

if (time-inPoint <= easeTime)
{[x_offset,y_offset] * linear(time,0,easeTime,0,driftSpeed) * (time-inPoint)}
else
{[x_offset,y_offset] * driftSpeed * (time-inPoint)};
