Norway SAFT parent account config question 4 digit Parent

Summary:

Norway SAFT parent account config question. We would like to use the 4 digit Norway Account.

We have our current Natural Account structure 7 digit GL account as Child and we have a current hierarchy 2-3-4-5 digit parent account structure

we already have some of the 4 digit parent account used in our Corporate hierarchy like 3000 - Equity, but 3000 in the Norway structure is Actually REVENUE

My question is do we allowed to put N- or S- Suffix in front of the 4 digit child? If I put it It won't be 4 digit any more. But I can't use a Parent called Equity and assign Revenue accounts under it in the Norway SAFT Account Tree. If we export it out in any report it looks incorrect
