Multi-class rogue sneak attack macro

My barbarian just took a level into rogue, and i was wanting to have a macro set for their sneak attack daamge to be calculat3ed automatically. However, the only macros I can find use base_level as a reference point. What i am using is  ?{Sneak Attack|Yes, 1d6+ [[ ceil((@{base_level}) / 2) ]]d6 [Sneak Attack]|No, 1d6}. is there a way i can change thy syntax to reference my multiclassed rogue levels instead?

Assuming Rogue is your 2nd class, you should be able to adjust as follows: ?{Sneak Attack|Yes, 1d6+ [[ ceil((@{multiclass2_lvl}) / 2) ]]d6 [Sneak Attack]|No, 1d6}

my god you beautiful bastard! that is exactly what i was looking for. thank you so much!
