How to massive approve changes in CAB stage

How to massive approve changes in CAB stage

My organization handles up to 50 changes per CAB, its very tedious to create an approval for each one of them and send it to the CAB members for recomendation. 

Is there a way to massive approve changes? 
OR
Is there a way to at least configure default approvals for any given STAGE? in this way I wouldn't have to create an approval to each on of the stages
