On each board column add ability to recall or ignore parameters for a given layer. This behavior would emulate the ability to make presets "absolute" or "relative". Where absolute means that all parameters stored when the preset was written are recalled for all layers. "relative" meaning that only layers affected in that preset are recalled.

Desired Functionality:
Ability to insert a command object, much like adding new media, to a layer for a given cue (column position). On a given cue, for layers that we want "cleared", we just don't put media. However, for layers we want to display media, we put one. If we want a given layer to continue displaying whatever it was already displaying before the cue was called, we could put an "ignore" command object at that position. When the cue is called, that layer remains in the same state, whether it was blank or looping a video.

With this approach, one composite could be laid on top of another existing one that was already playing - no matter what order the cues are called in.

Use-Case:
Imagine running a show that cannot be built in predetermined order on the dashboard. Now add to that the requirement of showing a bug on, like a donation ticker for a fundraiser, on screen at various off-the-cuff moments during a quick-paced live auction. With this functionality implemented, the operator could call the bug at any time, now matter what else is on screen, and only the bug is pulled up on the specified layer - nothing else changes because we told Millumin to "ignore" applying parameters to those layers (leave unaffected by calling the cue).
