At the end of custom field number-columns it is possible to choose from 3 variations of number manipulation, but I would like to be able to create custom formulas within main tasks.
For example, if I have numbers in sub tasks I would like the parent task to display a specific number calculated from the sub tasks and then I would like the number at the end of the sections column to calculate based only from the numbers in the parent tasks.
It’s mainly used as a way of seeing the main tasks progression by use of a number system. ie “The % of sub tasks completed”
