Can I create BSP instances?

When planning the modular set-pieces I’d like to instance BSP brushes, so that I can change only one and the changes would propagate to other instances.
Right now I have to convert a BSP into a Static Mesh, export (because of the Lightmass warning bug), adjust the position on the grid in DCC, reimport into UE, clone it where i want it. Thus I can change the basic blockout tool in DCC and then export, with changes immediately propagating to all instanced Static Meshes. It’s such a waste of time. I just want to work with instanced BSPs. Even when the warning bug gets fixed I still would not want to convert BSPs into meshes, because thus I’d loose the chance to edit them in-engine. Any advice on how it could be done, if at all?
