My idea is to take the dowels & line them up. Then I'll evenly drill a hole through them so I'll be able to thread some yarn through making those different levels needed. Then I would gently tie up the tomato branch to the according level. ...
I think you want those dowels to have a good amount of strength even after drilling holes. If I was going to DIY myself, out of wood, I would use 2x4s or at least 1x2s as uprights. Admittedly, they might be more expensive than small dowels, but they need to be strong enough to take some weight even after drilling holes.

Do they make any yarn as strong as STRONG twine? I think you need a lot of strength in the strings, since if you just thread it through holes, the weight of every branch will be stretching the entire length of twine or yarn.
Also, it might be desirable to tie or at least wrap the twine around each upright, so that it is more like that length of twine supporting only the branches right on top of it. Then the weight would be transferred to the wooden uprights instead of stretching the twine or yarn for the entire length of the row.

Do the holes need to be closely aligned? It won't help any unless the uprights are all pounded into the ground to the
exact same height. I would guess that the holes can vary in height by a few inches, especially if the twine is tied to each upright.
Probably the uprights can be more flimsy if you have one upright for each plant, instead of every-other-plant or every-third-plant.
Maybe use light-weight uprights as plant stakes instead of row stakes: 2-4 stakes per plant, and still tie branches to twine wrapped around the stakes. Like making lightweight cages instead of Florida Weave. If the materials are much cheaper or free, you could use 3 times as many free uprights to get the same strength as fewer store-bought uprights.
