Is there a way to change the value of a timer?

I have a timer for a Power UP.

While you have the power up, the player is invincible.
Once the timer reaches 15 seconds, the player turns back to normal.

If you touch an enemy, I want to add 1+ second to the timer’s current value so that you get punished for it, making the invincible phase run out quicker.

Is there a way? There doesn’t seem to be an action that allows you to modify the value of a timer, unless I simply can’t see it. :sweat_smile:
