I would like to be able to append/adjust actively sorted values in a range. In other words to be able to handle data more like matrix formulas in excel. Currently this is done with collect, but there isn't a way to change the values being filtered individually. To that end I propose a =collecta() formula.
=COLLECTA({Return Range},"Action to perform",{Criteria Range 1},{Criteria}...)
This could help with various projects and tasks, and would open up more solutions for the program.
