[Script Request] 5e OGL double dmg dice on crit without rolling another number

Hello, I'm not sure if this is possible with the current API, but is there a script for the 5e ogl sheet that will do the following: -If attack crits, take the dmg die roll and double it and display it as one number, without showing a second 'crit die' or a preset value of '0' I would very much like to see if there is a script like this to show my DM. We use the rule where all crits are doubled, not that an extra die is rolled. Regards

The API can't change anything already sent to chat, only react to it... so this isn't possible. Your DM would need to re-write the html/css roll templates and put them in as a custom character sheet on their campaign.
