Filter multiple keys using cbbackup

Hello, I would like to ask if there is a way or command in cbbackup tool that can backup data from a bucket using multiple keys? Say for example I have branch bucket with multiple branch documents and I would like to create a backup of branch-0000 and branch-0001 at the same time.

Here’s a sample of my execution:
./cbbackup http://localhost:8091 /home/branch/all/ -b branch -u Administrator -p Password_1234 -k ‘BRANCH-0000’
