In Diversion, you can tag commits for easier reference of particular commits. 
dv tag [-sub-command] [--json]
To create a new tag: 
dv tag -c <name> [-a <description>] [--ref <commit_id>]
The above command will create a new tag with the name <name>, and optionally, you can add a description [-a “Tag description”]. You can also provide the commit_id explicitly, or by default, the current commit will be tagged. To delete a tag: 
dv tag -d <tag_id> [--f]
The tag ID must be Diversion’s ID, not the tag name.
