The idea is to have an option in the 'new formula column' (right click on column) that inverse a formula function.
For exemple, the formula of a column :z is:
:x / (1 + :y)
Then I select click on 'New formula column/inverse function'. Then a popup menu or an additional menu propose to select the independant variable. Let say I click on :y. Then a new column called Inverse[z][y] is created with the following formula:
:x/:z - 1
This features would be extremly appreciated for inversing transformation.
