@Murz thanks for the feedback, it’s been passed along to the team 
Currently you can export an Organizational vault in its entirety, although I can see how useful it would be to export a specific collection.
export Organization vault data from the web vault or CLI. Exports can be downloaded as plaintext
.jsonor.csvfiles, or as a.jsonencrypted export.
Alternatively some users export and modify vault data before reimporting for bulk changes, or use the CLI to automate processes with custom scripts.
