Mega/Bulk Sign

Hi There

I am fairly new to adobe and love and loathe it in equal measures!!

I regularly need to send out documents to be completed, signed and countersignes and use the request signatures feature.  I have now been told by a friend that I am making life hard for myself by not using the Mega/bulk sign feature. 

I would love to, but I cannot find this feature, my app is up to date but I am really struggling to find it.

I have a subscription to Adobe crobat Pro DC

Please help
