Is your feature request related to a problem? Please describe.
Meta icons do not inherit on-click features from their collective icons. While I understand there are some issues related to combat lockdown, it'd be nice for out of combat "buttons" to be able to have functions based on what they're displaying.

Describe the solution you'd like
It'd be nice if there was a checkbox on meta icons to enable Inherit Click Function from currently displayed icon, but it warned that it would only work out of combat.

Describe alternatives you've considered
Currently the way I see to do this is to simply stack two different icons directly on top of each other instead of combining them into a meta, so when one is hidden, the other can be clicked.

Additional context
It'd be even nicer if On-click animations/chat messages/whatever could have conditions, so a single icon could both start a timer if its not running, and stop it if it is.
