As someone who shoots analogue professionally and also retouches photos professionally, people downvoting you are being foolish and over-reactive.

Lightroom's removal tools are exceptionally well-tuned for removals - much better than Photoshops - and there's a **HUGE** benefit to being able to to do everything non-destructively within the same workspace as it lets you iterate and improve as you go. The huge issue, is as soon as you start getting into the 10s of removals, Lightroom grinds to a halt. 

**So here are some tips:**

**1. Save dust/distraction removals to last.** For your existing edited scans, I would copy your dust-removal settings to a virtual copy and then delete them from the main scan. Once you're done editing the main copy, copy them back from the virtual copy.

**2. Save dust removal for a photoshop stage later in the process.** This has the huge downside that it's destructive so you can never make any changes to the original RAW scan ever again without having to do all dust removals again.

**3. Generative Remove lets you make hundreds of removals at once.** This means you can select all your dust using the tool and LR will then do it as individual removals. *This saves* ***so so so*** *much time over doing it one-by-one.*

**4. Use Generative Remove as above, but change it to Content-Aware before triggering.** Unlike Generative Remove, Content Aware remove usually makes you select each removal one by one, but you can 'trick' Lightroom by using the generative removal tool to make your selections, and then hit Option-Shift-G to turn off 'generative remove'. Once you hit enter, it'll do all the removals as individual content-aware ones, which is faster and doesn't waste your credits.



Obviously this isn't ideal, and what's especially infuriating is this could easily remedied by a simple option to disable all spot removals just as you can with masks.... but alas.
