[Feature]: Ability to share selected benchmarks

### Problem or motivation

At present sharing benchmarks is an all or nothing process. It'd be better if we could share which of the benchmarks we wanted to share.

### Proposed solution

Either a CLI argument like `--share --only muse-glimmer` or an interactive checklist.

### Alternatives considered

### Feature area

CLI (new subcommand or flag)

### Would you be willing to contribute this?
