Describe the new feature or enhancement

I have a pipeline that creates an mne.Report per subject and per "run". I made up my mind "after the fact" and now want to combine the "runs" per subject in a single report.

It would therefore be nice if I could simply load the reports, and concatenate them into a single report.

Describe your proposed implementation

Not sure how the specifics of this would work.

Describe possible alternatives

The alternative is, that I re-write my pipeline to write one report per subject, including all "runs", from the beginning.
