Not quite, I have a wanted list of parts.
You know you you can apply order on Bricklink to automatically update 'have quantity'
Well can you do that with a donor set? For example, if the wanted list has a lot of axles, gears, liftarrms etc, and I have three donor sets, I can bulk add them (to the have quantity) and reduce the wanted quantity.
I know rebrickable has a compare feature, that will compare an offical set to a moc, but that is for an individual Moc, my wanted list has a whole heap of random parts from 6-7 Mocs.
I have a few donor sets that will include some of the parts required on the wanted list. Is there a quick way to add the contents of the donor sets (to update the have quantity.)
