Trigger/Condition for Group Parent not one by one with individual Children?

[candid fern]

Hi everyone! Here's my question: I have a group with multiple children in it. I would like to do something like set a condition on the group parent so that that condition happens to all the enclosed children without having to apply the conditon to each of the children individually.

Here's an example. I would like the group to have an alpha of 100% when "Has Target" is true and an alpha of 0% when it is false.

I know I can set all of the individual children to have this condition, but it would be so much easier to just have that condition on the parent. Then, you could just make any changes to just the parent and not have to do it to all the children individually.

I can't seem to find any way to do this. Either I'm missing something in WA or my "google-fu" is not very good at finding a solution online.

Thanks everyone!

groups are just groups. they dont have such a thing as conditions or triggers

I would like the group to have an alpha of 100% when "Has Target" is true and an alpha of 0% when it is false.
the quick way around that is to make an invisible/empty text aura that satisfies this, and then anchor the group to that aura and use "set parent to anchor"

children inherit their parents alpha

so when the empty aura goes to 0% alpha, so does your group. and the auras contained in the group are by default also its children, so that propagates
