When setting up a chart of account, the mandatory dimension settings, should be possible to choose "either/or" for different dimensions.

E.g. a chart of account has 2 dimensions, were either 1 or 2 should be filled in.

Meaning that if dimension 1 is filled, dimension 2 can be left blank. The same if dimension 2 is filled, dimension 1 can be left blank.

This either/or possibility should be for as many dimensions as needed.
