auto roll a crit hit table

ok all i am drawing a blank what i want to do is set up a weapon attack when a Crit is rolled to also roll from a crithit roll table. i have already created a macro and the roll table i am just drawing a blank in how to get the player character sheets to roll this. i am using the OGL Sheet. i know i could properly program a full macro that would roll an attack then if it crit roll this table and the damage as well.  but what i want to do is create a universal approach that can be applied to each sheets weapons is possible  Extra Points is i could also roll a critmiss at 1 roll as well

The crit fail would require a custom roll template (certainly possible with your pro status, but a bit more work). For the crit success table roll though, simply put this at the start of your crit-damage dice expression in your attack on the ogl sheet: 1t[table_name] ]] [[ crit Damage dice expression here e.g. 1t[table_name] ]] [[1d8 Note that this method will require you to fill in the custom crit damage value for the attack.
