How do I merge text objects?

So I am making a game similar to Angry Birds, and I have a text object that shows how much damage was done/score gained whenever a damaging collision happens. However, since there are so many collisions, a huge amount of the text objects appear. So I was wondering if there was a way to check if two damagetext objects are close to each other, destroy one and add the number it had to the other (as in if a 50 and 200 are close, destroy one and make the other 250). This would help clear the clutter.

How would I do this? Thanks in advance for help.

Use a timer behavior on the damage text. On damage, if a timer is running, add the new damage to the old damage. Then create a new instance of damage text.

Like here, Damage on collision with another damage, save damage number of first 1 to local variable, and destroy it, add to second one number from local variable.
