Windows

Is your feature request related to a problem?

Currently for all slots, I have to Find best for each slot individually. Paired with this missing feature, it is taking very long to check for item upgrades.

Describe the solution you'd like

There should be a Find best all slots button, which will use the default queries for each slot (again, see this feature request)
