Can you limit the amount of times a calc is performed on certain cells

Is there anyway of telling Excel to perform a calculation on certain
cells only once.

I have a spreadsheet that performs calculations that include a single
value stored in a cell. I now want to change the value of this cell to
apply to new data being added to the sheet but I don't want to change
the results of past calculations.

Any help would be appreciated.

It appears to me you wish to track scenarios. You can learn more about
scenarios using Microsoft's help function.

Personally, scenarios are not as friendly when sending to a supervisor. In
the world in which I live, we use separate tabs. To the extent separate tabs
or separate files are the not feasible for you - try the scenario approach.
It is slick.

Cheers.
