If I understand correctly, can right-click an event and select "Make OR block" and then if your event has multiple conditions, the action will only occur if just one or more of those conditions are true, instead of all of them.
I just made up an event, here is an example of what my example event looks like with and without the "Make OR block":
Without:
Player > On collision with another object > Lava >
Player > Is jumping > System > Restart Layout
Player > Is on ground (Inverted) >
With this one, the layout will only be restarted if the player collides with lava while jumping and not on the ground.
With:
(I know this wouldn't be playable but it's just an example)
Player > On collision with another object > Lava
OR
Player > Is jumping > System > Restart Layout
OR
Player > Is on ground (Inverted)
With this one, the layout will be restart if the player collides with lava, isn't on the ground, or is jumping, rather than if all 3 conditions are met.
I hope I understood your problem correctly and I helped,
