Average Purchase Price & Loss/Profit/Value

I am noticing that my avg cost for the coins I am currently holding is much lower than was paid.
Is my average price an average of all lifetime transactions or just for those I am currently holding?
Does this also effect my P/L? (on Port Overview page)
I would like to have an average & p/l on Portfolio Overview page that only reflects current holdings.
Is this possible?

Would you be willing to add screenshots?
