Auto calc dividend Amounts Interface

For me, it is not intuitive to add the ‘Banked’ amount as the reports I get from my broker for OS dividends is Gross and WHT.
I need to work out the Net.
This is not really a big deal, but it would be nice if you could add a ‘Gross field’ so that IF I entered say the Gross, it would would calc / suggest the net.
Or, when I enter a Net (which sometimes I do ), the system dynamically calculates the Gross and displays it.
• Why do you want it.
It’s a slight PIA
• How is this affecting you?
• Do you currently have a workaround solution? Yes, I have to get get out my calc and figure out that say 12 - 2.67 = 9.33 (I can do the easy ones in my head)
• Can we reach out in future to ask follow up questions about this idea? Sure
