Thank you very much for getting in touch.
I can see the problem where our single letter character option is limited. The combination of letters together would help solve this problem and I will see if our design team can come up with a plan to improve this.
As a possible workaround to this for you at the moment, we have noticed a few customers using symbols / non-ascii characters e.g. ⚜, ♠, ♛, ☂, ♘
I appreciate this might not be ideal and I have registered this feature request to help keep you updated on any development in this area of the diary.
Thank you for coming back to me promptly.
Thank you for logging this with the design team, hopefully it's feasible to develop.
That's a great idea! Not ideal, but for the time being as long as we have a clearly visible separate indication we can work with that. We went for a heart symbol for now.
Thank you Ewan, you have been really helpful.
Have a lovely rest of the week.
Please could you include the full list of available symbols to use?
