As you may know, adding custom fonts would have bad effects on the performance of the page. So we think when a user wants to use a custom font on Depicter it is not to use only for Depicter and probably he is going to use it in other places on his website as well. That is why we decided to add the below option.
You can first add your custom font to your theme, most of the themes have this option and also there are plugins to do that, and probably you already have that font on your theme uploaded. after that, you can simply select the inherit from theme for the font of the text you want.
I hope this helps and please let us know what you think about it.
