Non-linear process flows

Is it possible to use non-linear process flows? I've played around with Novu today and while I haven't explored everything there is just yet, it sort of just seems that exactly one or zero things must happen following another. I have attached a notification process flow that I'd like to try to implement in Novu. As you can see I would require some sort of conditional logic or "if-else" statements. I could use filters, but I ran into a lot of complexity with them because everything would still have to pass through every step unconditionally. It would also mean that, for example, I would have to create like 10 different "send email" steps, with varying filters, to satisfy all of the conditional logic. It's just too messy, unmaintainable and unorganised for me. Does anyone else have this issue? Maybe it would be better and create many different workflows that simplify and separate this logic? It wouldn't really fix the issue but at least they would be more organised. Let me know if anyone had this issue or if you have any suggestions please. Thank you.
