OpenCore SSDT EC + USBX separate files?

Hi, so I'm building a Success' href='/2020/12/install-macos-catalina-on-supported-pc.html'>Catalina usb for a Z370 mobo and Coffee Lake i7. SSDTTime spits out all of the necessary SSDT files, except for the SSDT-EC, which doesn't include USBX information. The USBX.aml is provided as a preconfig file for all/most Z370 boards on the Dortania guide. Should I include these as separate files in the ACPI folder or combine them into one SSDT-EC-USBX.aml since that's what's referenced throughout the guide?
