UNREAL UE4 - How to create a countdown, reloading with multiple time options.

Hi, i´m working on a multi-countdown, it restarts with diferent end times, but branches only give me 2 options, true and false, no idea how to make my countdown go from option 1 to option 10, instead of 2 options with a Branch, nor any idea how to restart with my first option.

for example: if the countdown starts at 15 seconds, when it stops at cero, i want it to reload at 5 seconds, then at 10 seconds, then a 30 seconds and when its over, re-start to the first 15 seconds (option 1), but i dont know how to add so many options (because this depends on “beginplay” and “timer” its set like a tick, so i canot make a continuous chain of nodes and use delays between each) and also how to re-start with the first option.

Here is my BP:

Please help and share your BP ideas with images.

Any one of these nodes should give you what you want.

Perfect, thanks a lot!
