Withdrawal fees from Exchange broker

Hi,

I transfered 100 matics from my crypto broker account to my Ledger cold wallet.

As my crypto broker account and Ledger cold wallet are well synchronised, it appears as a transfer on Koinly (It’s perfect!).

The broker charged 2 matics for for what he considers as a withdrawal to an external wallet. These 2 matics are tagged as “costs” by Koinly (not perfect!). Can I add the value of these 2 matics in the adjusted cost of my 100 matics?

It would reduce my capital gain (or loss) when I dispose, swap or sell these 100 matics instead of being a cost.

Thanks!
