Extending number of available attributes for DFFs

Good day everyone.

This question is not specific to just Receivables, but we do have a need on the Receivables side to expand the number of the available attributes for us to use for some of the existing DFFs, specifically at the customer account level as well as the transaction type level. At this point we have used all of the available attributes (for customer account it is up to 20 DFFs for example) and we have a need for a few more to be able to store certain customer information at the account level rather than at the site level.
