VK_IMAGE_LAYOUT_GENERAL and separateDepthStencilLayouts

If format is a depth/stencil format, and initialLayout only specifies the initial layout of the depth aspect of the attachment, the initial layout of the stencil aspect is specified by the stencilInitialLayout member of a VkAttachmentDescriptionStencilLayout structure included in the pNext chain. Otherwise, initialLayout describes the initial layout for all relevant image aspects.

If format is a depth/stencil format, and finalLayout only specifies the final layout of the depth aspect of the attachment, the final layout of the stencil aspect is specified by the stencilFinalLayout member of a VkAttachmentDescriptionStencilLayout structure included in the pNext chain. Otherwise, finalLayout describes the final layout for all relevant image aspects.

If layout only specifies the layout of the depth aspect of the attachment, the layout of the stencil aspect is specified by the stencilLayout member of a VkAttachmentReferenceStencilLayout structure included in the pNext chain. Otherwise, layout describes the layout for all relevant image aspects.

How do I set VK_IMAGE_LAYOUT_GENERAL for only one aspect, not both?
For example:
depth: VK_IMAGE_LAYOUT_GENERAL
stencil: VK_IMAGE_LAYOUT_STENCIL_ATTACHMENT_OPTIMAL
