setting mp3 bitrate (VBR-CBR)

Hello, just started learning about macros. It looks like I am only missing one piece for my macro string. I want to be able to set the bitrate to a specific setting but I have no idea which macro to use for that. Can someone give me a hint please?

Windows 10
Audacity 3

Unfortunately Macros do not yet support specifying MP3 settings, only the basic file type (WAV/MP3/etc).
Macros will use the setting last used by Audacity for exporting MP3, so the workaround is to export a dummy MP3 file in the required format before running the macro.

Adding exact format support to macros is on the developer’s “to do” list.

Thanks for the response. Thanks for the idea for a work around.
