My question is about weighted marks within an assignment group.

It seems that Canvas will only allow the total group assignment to be weighted if the 2 assignments are given marks which add up to 100 ( e.g. Assignment A = 70 and Assignment B= 30 marks). 

I have an assignment group worth 20% of the total grade. Within the assignment group there are 2 assignments (A & B) both marked out of 100. Assignment A is worth 70% of the total assignment group (20%) and assignment B is worth 30% of the total assignment group (20%). 

Can Canvas calculate a weighted  assignment group when the sub assignments are both marked out of 100?
