Change basis of a security on Interactive Brokers?

Is there a way to change the basis of a security traded on Interactive Brokers?

I have my tax basis set to LIFO but I've been trading oil and it didn't calculate my P/L like that, it calculated it with FIFO, is there a way to go in and change it for that specific trade?

 

there is.look in account management,on their website. i believe it's somewhere in "reports' section

 

There is tax basis declaration where you can choose LIFO or FIFO but it didn't apply to my futures trading, can I do it for a specific trade?
