Currency conversion cost management

Hi there,

I am based in DK and use SaxoBank. Since my base currency is DKK, almost every transaction has a currency conversion cost.
That can be easily managed for the buy transaction applying the proper conversion rate.
However, when looking at the portfolio value, I shall consider also the conversion cost for closing the position (e.g. the market value of a position in portfolio is currently 10000€ /74.616DKK and that’s the value shown by Portfolio Performance, but in reality I know that when selling the position I will need to pay a conversion commission of 0,25% that take the real value of the position for my portfolio to 9975€/ 74429DKK).
Is there any way to manage that, in order to get a valuation of portfolio that considers the exchange commissions?
If not, could it be considered for a feature?
With the same logic, could it also be possible to treat the selling commissions in the same way?
Couldn’t these be optional parameter for the transactions operations?

Thanks
