Actor sequence components

I’m trying to use these in my animation project, and wanted to know, whether they can be parametrised? I have ten pairs of static meshes that basically need the same animations, both open and close, and the animation is rotating each mesh in the pair by the same absolute angle, although the sign may change.
Doing 20 AS componnets seems like an overkill, so I wonder whether there’s a way to parametrise them?

Cheers,
