For the time being it is possible through changing the name in language file.
For instance we want to show something else on checkout page in Blesta. In order to change or rename the “Offline Payment” label you have to go in your blesta directory as follow:

$lang['Offline.name'] = 'BTC, ETH, LTC, Tron Manual Payment';
Now let’s see what the checkout page is showing.
