Motion tracking: how to link an object that does not have that track?

Hello

I have a video, it is a landscape, and the camera moves from left to right. I want a flare that appear on the right side. There is a point which is still in the picture, I used this point to follow the movement.

But the problem is, when I want to connect optical flares with the track point, the flare is always about to follow-up, but I want a little more on the right side...

How is it possible to link an object that is not exactly about to follow-up?

Usually apply you tracking to a null value information, and then use an expression to link the position property of whatever it is you are trying to attach to null with a simple expression. If you need to update the position then you can either add value + at the front of the pickwhip expression generated or and sometimes it's better, add a second null, 2 null null parent 1 and then use a transformation expression space layer on the position property of your effect. The expression looks like this:

p = thisComp.layer ("Null 2");

p.toComp ([0,0,0]);

I don't if I did not properly understand the problem, then please post a screenshot of your project with all the properties for layers in question revealed.

Here is what something would look like:
