Convertible Notes "Product" Question - "SAFEs"

I know start ups are using discounted convertible notes to finance prior to getting pre VC or PE rounds of financing. I know "carta" has tools to "issue and fund" the notes thrugh their platfor. My question is do you know of anyone that has a service that tracks the loans, lenders, interest accruals and provides the lenders reports to see their total portfolio value? We were having this discussion at a board meeting recently and none of the board members or team knew of any such platform service beyond an excel spreadsheet. Do any of you know of such a tool? We are thinking it might provide a value to the ETA market as well and could be added to our product offerings. Let me know. Thanks
