Adding a multi option to exports
for example:

1. allowing -f to take more than one format. or something like -f "json,csv,plaintext,htmldark" this way you can get several formats without having to hit the api several times. that will require some processing power but should be useful to those who want
2. allow multi option for other things. like for example -c I can see @Tyrrrz already had accepted something here Rework CLI commands to be composable via piping #1522 (comment)
3. maybe allow reusable thing. for example always export the json then allow the user to get whatever after the last export point? I think the json have a lot of the metadata of the export formats
