Hello,

I know in SharePoint 2013 On-premises there is a task delegation function/feature that is when one person is not in the office, his/her task can be able to delegated to other people. Now I am working on creating a Nintex workflow in O365. Does the O365 have such function or feature? 

I attached a screenshot which is the delegation in SharePoint 2013 On-premises.

Thank you,

Yong
