Reverse TCE Calculations for TC estimate

In IMOS, users are able to reverse calculate the details for a hire just by changing the TCE number to the targetted number. (i.e. i type in my target TCE and the system tells me what gross rate I need to achieve my desired net TCE)

however, for time charter, this method is currently not working which is very inconsistent in your designs. It would do wonders and improve user experience if you develop this feature into your current IMOS platform.
