Asset Managment Question

[mroadster]

New to MMEX, transitioning from a very outdate MS Money. I am running the Mac version of MMEX.
In Money, I have an account where I only really track the monthly balance, basically just an asset account. In Money, I can just click a button to update the current balance, and it will calculate the debit/credit transaction to bring it to that amount. Is there a way of doing this with MMEX? I've created the account as an asset account, but it behaves exactly like any other cash or chequing account. On the features section of the MMEX site, under Assets, the description does not match what I'm seeing in the Mac version. Am I missing something? My Edit Account screen for an asset is identical to that of a cash or chequing account. As a workaround, I guess I can calculate the debit/credit and enter that as a transaction.
