Cost per transaction

Dear Sir,

We find the Mollie plugin very stable to our satisfaction.
There is one question we have:
In our country, every Mollie IDEAL transaction costs 0.29 Euro.
We are looking for a way to get this cost on the wordpress database linked to the concerning woocommerce orders.

Do you know of any way to do this? And wouldn’t it be a useful feature to have within the Mollie plugin settings to indicate the cost per transaction?

P.S. Once on the database we can include these costs in our a reports.

Thanks,
With regards,
DV
