Notes for editing icons:
- lists are entered by separating elements with forward slashes, e.g. 6/12/18/24
- in a macro, this would be expressed as [6,12,18,24]
- dates should be in YYYYMMDD, YYYY-MM-DD or YYYY-DDD format; some icons accept dates in relative format, e.g. -1 = yesterday, 0 = today, etc.
- times should be in HHMM or HH:MM format. If MM is omitted it defaults to 00.
