I didn't manage to find any documentation that for example you can add a shared audiosource to a list of buttons as an event trigger. The standard way I saw was to drag the source to each of them manually, which is a little bit annoying.
For example in a tutorial : https://www.youtube.com/watch?v=LD2gfUKkMD0&list=LL&index=1&t=8962s
for example to apply to these buttons
you need to drag them to event trigger manually.
Would be kinda nice if there is a feature for example, you ctrl select list of buttons, and you apply audio source, then it applies to all of them.
If this idea has already been developed, please close this issue, and apologies.
