How do I use 'AND' and 'OR' conditions together?

Basically I want to test something along the lines of

'If Cond1 AND Cond2 are both true, OR if Cond3 by itself is true, do something.'

Or in other words, '(true && true) || true'

As far as I can tell, I'm only able to turn an entire block into a bunch of single OR conditions.

A simple way would be to put the 'do something' part in a function, and have two separate events. Or just copy the actions again in both events.

Cond1 is true | call DoSomething()

Cond2 is true |

Cond3 is true| call DoSomething()

You can go old-school with Compare two values:

First value: (Cond1 & Cond2) | Cond3

Comparison: equal to

Second value: 1

Example: (value1 = 2 & value2 = 3) | (value3 = 99) "equal to" 1

Oh well. I was hoping there'd be a way to set it up without just having another entire block of actions.

Thanks anyways.
