WTH can't I set on and off delays on Template Helpers?

Why can’t I set delay_on and delay_off in Template Helpers?
It is very annoying that I have to use YAML for that…
Could this be implemented?

Best regards

I already created this WTH. please vote here WTH Does the threshold helper not have delay on and delay off also another one there WTH isn't it possible to define delay_on/delay_off in UI for template binary sensors?
