Im sure this has been asked for because this would be extremely powerfull for mograph power users and repetitive animation tasks.
Currently there is one bindable shortcut to reuse the last animation preset. If we had the ability to keybind our saved animation presets (lets say 1-20), that would open up a whole new world of functionality. Using the numpad or hardware (like Elgato Streamdeck) for presets without the need for extra plugins would speedup the workflow for some users in a very big way.
