” Batch processing ” is the term we use in photography for editing one image perfectly, then commanding a computer program to make all the rest in the job the same. It saves an immense amount of post-processing time. ( Working with really lousy images is known as son of a batch processing…)
It is also the thing for a lot of the scale model tasks we do. You could cut each individual part off the sprue tree, finish its edges and gate points with sandpaper, then undercoat and spray it separately from the rest. Then pick up your knife and repeat the process of the next part. A tank model with multiple wheels and track links could occupy you from now until the van arrives and the nice men in white coats take you away.
Or do as the instructions urge: spray similar parts on their sprue trees and touch up the gates when you finally cut them off. This approach is scorned by some, but the van is circling the block…
When I have separated things I use the doubled-up piece of cheap masking tape on scrap card to locate the parts for the spray – not using rubber gloves to hold the parts. It’s surprising how much force there can be from the nozzle of the air brush, so you need to tie things down before you blast them out of the spray booth.
