Does ISACCTYPE work for ASO?

Summary:

We are hoping to leverage the ISACCTYPE function as a member formula. We are looking to leverage the Acct Type to "flip" signs and/or aggregate as needed in Freeform ASO

Content (please ensure you mask any confidential information):

We want to flip the sign on Revenue, Liability and Equity accounts so that they can appear as a Trial Balance view. Additionally, we want to aggregate the Account Types (Revenue and Expenses) for QTD and YTD calculation. Currently we are using ISUDA, but would like replace and use account type if possible.
