Cost base in the holding currency

I have some holdings in dollars. Some of them come from a euro account and cash balance, others come from a $ account. In both situations you show my cost base per share in €.

In the second situation at least, but for both actually, I have always the problem not to be able to know at what price I bought the stock. I literally have to change website and check in my specific platform the $price I have bought, INSTEAD OF CHECKING THE PORTFOLIO TRACKER SERVICE I’M PAYING FOR. I mean, I really love your platform but i think it is due to have this super basic info from my billed portfolio managing service…I think it could bring value to your platform.
