Feature Request: When editing a set for a synced ilvl, add the ability to choose 'fully synced' items that are 125 IL above

[VioletHynes]

Currently, when making a set for ultimates, it's very common for much of the general recommendation, part of BiS, or set to compare to BiS to have synced down items, i.e. any item 125 IL above the sync that has the same stats. It's possible to choose a specific item and xivgear will sync it correctly, but that can give the illusion that the set is recommending that specific item to someone less familiar with how IL sync works.

It'd be nice if there was a generic 'synced item' option, or perhaps when you choose any item that's synced down, it transforms (could be a transformation in view mode only) to show the minimum item level required and display all of the alt items.

In essence, I think this UX is really good for ultimates, and others agree (I've been asked a few times how I 'added synced items' for a set): https://xivgear.app/?page=sl%7Ca31944c3-a9ca-4839-ba67-2e3ec23dabb2 -- it especially works great with the alt items feature, and ultimates are a common thing to need to provide gear for. This viewing experience is already great, but it'd be even greater (and easier to author these sets) if synced items were more first-class.

I love the ultimate set UX for xivgear, especially being able to compare 'lazier' gearsets to BiS and this would really push it over the top to be even better.
