Extend Unit Timers

[The Howling Storm]

Is it possible to extend (increase the remaining time of) a unit's expiration timer using GUI, or at least no more than the most basic of JASS?

It's not possible, sorry. Expiration timers are fixed and cannot be removed or extended.

You may want to have an alternative, such as triggering the expiration and giving the unit a buff to signify that it is going to die, or whatever.

If it is a simple unit (a unit without inventory, or buffs, or whatever), such as a dummy for a spell, you may want to remove the unit and then recreate it (and attach the effects or w/e).

You can also use Floating Text to indicate the timer for the unit's expiration timer.
