I have added holiday calendars for UK, Canada, USA, and Australia which display as expected, however, on a day such as 'Christmas Day' there are 4 such identical entries listed. On the windows app, moving the mouse over each just displays the same rollover text 'Christmas Day' it does not specify which calendar it came from.

When configuring each 'external' calendar it would be nice to be able to add a text 'PREFIX' to be added before the calendar even text such as 'UK', USA', such that 'UK: Christmas Day' and 'USA: Christmas Day' would differentiate each.

Due to the limited color selections, it is hard use this method.

Thanks!
