[chimerax-users] Transform a group in a single structure

Hello, when a I save several models in a single mmcif file and I need to open it for a different purpose in ChimeraX it appears as a group with several submodels. Does anyone know how to convert this group in a single structure with no submodels? Otherwise, how can I save them to have a single model?. I used to use copy/combine in Chimera but I cannot find anything similar in ChimeraX.
