Got the perk for crafting components and turned out I have thousands of them and for crafting each one of them I need to hold mouse button for two seconds or so.
Can we instead have a slider for it? It consumes awful amount of time and major turn off.

This. I also got the perk, but it turns out I'd have to spend an hour or more holding a button to turn them into what I actually need. We absolutely need a mass crafting feature.
