Cap data plan Top Up Validity Period required

Hi we are currently using splynx 2.0 in production and would like the following features to be added with respect to Cap data plan Top Ups.

  1. Column in both services and Invoices to display cap data plan Top Up Validity Period (i.e. recent topup start and end date)
  2. Option to set notification via email and sms to inform customer of approaching top up data deadline. So that the customer would do the needfull to top up to enable rollover of credit.
