Ability to filter / restrict actions by device type

[bcmitri]

Is your feature request related to a problem? Please describe.
As it stands, I have the ability to define a single list of actions and this list is common to my iPhone and my Apple Watch. Since each device represents a different interface and a different set of use cases, I'd like to be able to set a different list of actions for each.

Describe the solution you'd like
I imagine a solution where each action I define includes options for iPhone, Apple Watch, Both, and possibly, Neither.

Additional context
I'd like to implement something like this on my Apple Watch:

However, I don't necessarily want to disrupt the actions I currently have defined for my iPhone.
