Creating RollForward type reconciliations and creating external reports

I'm working with a client that would like to create a roll forward type analysis within an Account Analysis type reconciliation.  My initial thought is that the transactions the client would input to support the balance in the reconciliation would look something like this:

Example - Prepaid Rent Account

Description - Contains Name of Vendor

Attribute - list type attribute breaking the amount into a meaningful detail (i.e. Beginning Balance, Prepaid - Next Month, Base Rent, Maintenance etc)

is this a feasible approach ?  Is this considered best practice or could this set them up for issues down the road ?
