Dimension interval for G/L Account

Hi

Probably I already know the answer to this, but I have to ask if anyone have solved it.
I have a customer that want to setup a dimension interval restriction for specific accounts.
Example:
When posting on G/L account 5820 it is mandatory to use PROJECT values 1-4
When posting on G/L account 5920 it is mandatory to use PROJECT values 5-8

This could be realized by blocking the PROJECT values that are NOT allowed in Dimension Combination, BUT that is only available to configure for combinations of Ledger Dimensions, not G/L Accounts. ](*,)
Is there any other solution to set up combinations between G/L Accounts and Dimension value intervals?
