Linear Patern Along a Curved Surface

I am still very new to CAD altogether so I'm looking for a solution that fits within my current knowledge. I'm trying to add a cutout on a part and copy that cutout across the part. I want to be able to adjust the overall length of the part and still have the cutout work. The cutout will start at the top, a flat face, and needs to end half way down to a curve. This depth to end will be different depending on where the cutout is.
Here is my sketch: https://cad.onshape.com/documents/0f68e4ff43da893d08ce530f/w/79b9fc08973cd06177e7c6b9/e/1e7e7dce16acfea7d1940d24

Off of the top of my head, you could extrude a surface, then make an extrude remove up to that surface, linear pattern that extrude, then delete the surface.
Matts way is good if you don't mind the bottom of the cutouts not being totally perpendicular. I suspect these will be used for slotting together other laser cut pieces or something like that, in which case I'd want the bottoms of the cutouts squared off. Here's a way to do it using a Linear Pattern of a number of features including one that measures the distance and halves it for the depth. I used my custom Linear Pattern Plus feature as well so it will update the instance count to match the total length of the spine. https://cad.onshape.com/documents/42251c285060af9735584efa/w/dbb7883f7cb815784dcef851/e/37044636890653a11379dc86
