Old idea that needs attention: Tag a version as completely Locked

Possibility to tag a version as fixed, so changes in parameters and formulas do not impact the data anymore. This is really important for improving the reliability of the data for customers that want to be able to calculate multiple versions at the same time. If a formula change is needed in that case old versions also change. So for example the budgat that is their pount to compare with and should not change overtime. I know it is possible to create reporting modules that copy the data and store the final results, but most customers want to be able to drill down and store the full version for reference. #FixVersions, #DataReliability
