Hello @joev,
To replace the currently used font with your custom font will require higher code customization and as much as we would love to help you with this we are unable to do so it is beyond the support we offer for our product.
So if you want then you can hire our professional developer. To hire a developer refer to the below given link:

If you have any query/confusion further, kindly let us know.
Thank you.
