How to add countdown widget in multiple levels blueprint ?

I want to make countdown timer widget for different levels(different time values) without using game mode.
or any simple way to make countdown timer for levels which i can change time values for different levels.

game mode would be a good place but if you insist on not using it then i would probably make an actor which holds the script you need. that way you can just place the actor in each level and set the time via a public variable. of course as with everything it depends on your game, there could be other solutions.
