Reply to Load FX Presets Mapping

So I searched all over but couldn't figure this out. I have seen many mappings that allow you to load a preset fx chain or a single effect with a button and i want to know how to map this.

For example hitting a button loads beatmasher filter and gater into fx deck 1 then hitting another button loads a different chain of fx.

Then in fx deck 2 i want to be able to hit different buttons to instantly load different single fx.

Thanks for any help guys.
Much love
