Add internal notes on surcharges and discounts.

I have a situation where I would like to add an internally visible note to multiple surcharges that look the same to the guest but are different use cases internally such as a different commission percentage or things like that.  

Or have the title we see in OR be internal vs what the guest sees. 

When I passed this over to the engineers, they came back with a truly out-there interim suggestion...

Add a unicode emoji to the surcharge description.  It will be meaningless to the guest, but would mean something to you.

For example, you could use things like moon cycles of unicode to indicate percentages:
 
🌑 🌒 🌓 etc
