Change Signal of accounts only in the SmartView

Hi,

I am currently using HFM 11.1.2.4. Currently the values are loaded to hfm and appear all in absolute value and according to the account type it substracts or adds to is upper level.

For the client is easier to see revenue values as positive and expense values as negative.I thought changing all accounts to have the same account type, but functionally it doesn't sounds a good idea.

Is there any way, in terms of reporting (meaning smartview) to show the values as negative if the account type is liability or expense?

Thanks in advance,
