[5E Shaped Sheet] Turn off Proficiency Bonus

Hello, I could really use some assistance. I really love this sheet, but I can't find any option to customize the Proficiency Bonus, for both PC and NPC sheets. I'd like to turn it off, as mentioned in title, but being able to edit it at all would be good to know.

If you go into the settings page on the character sheet (the gear icon) and change Proficiency Bonus (near the top right) from "By Level (Default)" to "Custom," you can make it anything you'd like. ETA: this is how the 5e OGL sheet works... apologies if that's not accurate to the Shaped version

Hmm I don't see any easy way to do this globally.  On the attributes & abilities tab of the sheet there is a pb and pb_display field, but that doesn't change the roll when you have the proficiency button checked on a saving throw for instance.  Obviously you could just not check the button next to saves and skills to avoid proficiency to those items.  For spell dc on the settings tab there is a base dc field you could modify.  You could use modifiers on the right side of the character sheet tab to automatically subtract the prof bonus to attack rolls including spells.  there is also a modifier field for spell dc, that may be a better place to remove the pb bonus for that. If you have a pro account and access to the api, you could probably do this globally.  I think the hidden field which controls it is proficiency_bonus.  

Real shame there isn't a setting, but it seems I'd have to a minus modifier on rolls, at best. Thanks for the replies and help.
