Many instances of same entity in sketch, linked/synced/etc, or copy+paste with equal constraints?

Basically the same question as this old one from 2015 https://forum.onshape.com/discussion/279/copy-sketch-elements-within-sketch
I have a sketch where I need to place around 50 arrows, but I don't know the exact dimensions of them yet (and it may require some tweaking and multiple passes to get the fit I need). They'll all be in different positions and have different orientations. I want to be able to place them all, and then edit the original and have them all update, similar to how a linear/circular pattern does. The only way I can find to accomplish this at all is to have every component of every arrow have an 'equal' constraint tied to the original, but that'd require me setting up 8 constraints x 50 arrows one by one. I had assumed just making one copy with these equal constraints, and then copy-pasting that copy would work, but the copy-paste seems to lose any equal constraints that reference another entity, so that doesn't work

I agree with @S1mon, this seems like it would be better done at the feature level...
But if you did need to do it in a sketch for some reason, you should be able to dimension the first arrow with variables and then copy and paste the first arrow like this:
