tricky painting advice needed

I have just painstakingly prepped 22 cabinet doors and drawer fronts for repainting.
These doors have both small insertion and bolection mouldings on them, and were previously painted with an oil based semi gloss. After trying my best to clean the mouldings with sugar soap and a nail brush (toothbrush for the corners) then pressure washing, towel drying, then compressed air, I sanded as much as i could even using one of those sponge sandpaper blocks pressed into all the contours on the mouldings. I then primed them zinsser bin shellac based primer (2 coats). For those who have used this primer you will know it flattens out beautifully, is as hard as nails and cannot be scratched off. I would like to apply 2 coats of oil based semi gloss over this but don't want to go to the trouble of sanding again between coats. Every article I read about oil based paints is that you either have to sand between coats or undercoat again to give bite to the top coat. I know I could lightly sand the flat sections easily enough with a piece of wet and dry, but the kilometers of the beading with all its rounded and shouldered contours is daunting especially the corners.
Question is, is there a time frame between drying and curing that a second coat will adhere to the first coat without the need for sanding or re undercoating?
