'Master Set' to aid in gear change and build comparison

Is your feature request related to a problem?

When making multi-faceted gear changes, it is difficult to isolate the updates, and compare to the original state.

Example:
If I'm adding the capacity to gain Frenzy Charges, I need to not only change gear, but also add the check box for "Do you use Frenzy Charges?"
When checking to see how this affects my damage, I need to compare DPS while wearing the new gear that adds this capacity (equipment set), and then check the box for Frenzy Charges. (See issue #4874 for the custom modifiers on the configuration tab - this request is for the whole tab, and more.)

Describe the solution you'd like

IT would be easier to compare upgrades that span multiple sets or non-set related items if there were:
sets for Configuration settings,
and a "Master Set" that combines multiple sets into one easy to swap to configuration.

In the example above, I could create a new gear set (exists), a new configuration set (does not exist), and a "Master Set" that automatically switches to a defined set of each type. Ideally, this would allow for mouseover stat differences, or a side by side comparison of the stat window (left hand side skill/hp/resist preview).

Currently existing sets:
Gear
Skills
Atlas Passives

Needed Sets:
Configuration
"Master Set"

Describe alternatives you've considered

Currently, I can either open two instances of the program with the same save file (sketchy, and prone to odd behaviors), or save my build, take screenshots, then adjust settings. Both of these options are clunky and less than optimal. When working with a single monitor, this is even more difficult.

As an alternative programmatic solution, I would suggest the capacity for adding a "freeze frame" of the left side stat window, so that the original state can be viewed and compared side by side. A further enhancement would be an option to highlight changed stats, such as +55 (+1%) Life.

Example of Build Comparison

Nell’issue non sono identificati file, test o punti di ingresso. Inizia individuando le implementazioni esistenti dei set Gear, Skills e Atlas Passives e la scheda di configurazione. Il lavoro sarebbe completato quando fosse disponibile un flusso funzionante di Configuration set e Master Set e il comportamento richiesto per il confronto delle build fosse definito e coperto da test appropriati.
