I can see it being useful - but the amount of effort required to implement this would be quite high and it would be hard to justify the high level of effort when there are also many other "important" things that could also be done.
You are also the first person I have heard asking for this.
The plugin does allow sessions to created using a CSV file, it might be simpler to improve that process - to allow session delete/update via CSV.
Of course - if you really want this...and you have internal development capabilities, pull requests are always very welcome!! (If you are interested in funding the time for me to work on this, feel free to get in touch privately.)
