Billable Time include as an option in customer portal

Dear all,

ideas I’ve got an idea or suggestion to include Billable Time as an option in customer portal.
The billable time per client is recorded in the Billable Time module. Currently, this can be converted into a sales invoice, although only the date, description, hourly rate, and time spent are transferred. Within the Billable Time module, we use custom fields to record the work performed. I would like to offer the client access to this (via the Customer Portal), so that the hours spent are available to them in detail.
However, the option to specify when certain fields are visible or not (and related settings) to the client in their own client portal must be added.

Thanks,
Canefield
