I liked the possibility to create custom fields and functions in Freshdesk Analytics, but I like to suggest some pretty basic improvements.
Even though I can subtract values, it is impossible to make operations on negative values.
I can't use ADD_DATE(Created date, -7).
One other thing I tried is to create a "Quarter" field like:
CONCAT(YEAR(Created date), "Q", CEIL(MONTH(Created date) / 3))
Analytics doesn't allow to convert integer to string.
