It would be very convenient to have one or more calculated function that allows you to change the behavior of a master object. This would allow you to paste the same object several times, changing for example the year to which it should refer in the calculations. Within the calculation formulae it should be possible to introduce a parameter (such as $1, $2...) and to define the parameter in the object with a variable or a further calculation. In this way, to create for example 10 different KPIs that refer to 10 product categories, it would be sufficient to define one in the master items and then, once pasted on the page, just change the $1 parameter to which the internal formulas refer to have all the KPIs done quickly.
