Tax & automatic net calculation

Hi everyone,

I, as an Italian user, do not have the possibility to set a standard amount of tax % to be applied to the entire portfolio. I see others can.

Anyway, since I know what the standard % is in my country, is it possible to automatically calculate and inputed the breakdown Net , tax and gross for dividends?
In fact the dividend you automatically populate show just the gross: with the simple input by the user of the tax %, you could save him tons of time automatically adjusting it in net, tax and gross.
