Mixer Panel Layout switching through Actions

[Flareless]

I use a couple of different Mixer Panel Layouts when I'm working;

Options -> Layout -> Mixer Panel

I switch between a few of the different layouts depending on what I'm doing.

I'd like to add buttons to my Toolbar to do these actions (e.g. Mixer Standard, Mixer Strip, etc..) but I can't seem to find the Action to perform this operation.

Is there an action to perform this function so I can automate it?

There are two stages:
(a) On the Screensets / Layouts window, assign the layouts you want to the Actions
(b) In Customize Menus / Toolbars, assign the Custom Layout actions to toolbar buttons
