I assume you mean Patroneo, from your last post.

Not in the program itself. Please note that "complex songs" are the opposite of Patroneos written design goal. It is the "easy sequencer", which also means not offering too many options.

If you want automation you can send out midi notes as normal with a Patroneo pattern and then convert them to CC or similar with LV2 plugins in Carla, where you also can use these signals to automate plugins etc.
