Is there any way to move a timer window (created with the timer actions) to a specific point of the screen just like you can do with a dialog?

I don't believe there's an action to do that....

If it's absolutely necessary to be able to move it, you can make an integer variable that counts down using a periodic trigger, and display that number as dialog label text in a number of "time" formats (hh:mm:ss, mm:ss, etc).

Yes
Actions -> Timer -> Move Timer Window

Lol when the question was asked that action didn't exist. I'm glad to see they added it.
