Thanks for your response and the info.
Thinking about it, maybe one could create a series of volumes and mask away the density of the symmetric copies so that you’re left with the asymmetric unit?

If you have an atomic model of an asymmetric unit fit into the density, you could extract a box around it using Chimera volume viewer menu entry Features / Atom Box. Or you could extract the density just at grid points within a specified distance of atoms using volume viewer menu entry Features / Zone…. To save the results of either of those methods use volume viewer menu File / Save Map As….
