Different timer behavior for each copy of object

I'm trying to give a different duration for each copy of object with timer behavior.

If I give the same tag I can't compare the different duration values.

If I give a different tag like this only first object is moving.

Here is a capx: https://db.tt/jz3qL1Qp

See where it says pick nth= 0?

Its only picking the instance that ='s 0

Don't use system, use the objects conditions like:

On start object set variable "go" to 1

Then use the variable to move the objects

object variable go =1 set x to self.x+ blah

object, on timer set variable to 0

No need to make unique tags.
