Hi Shubh,
In my opinion, we can't achieve in standard way but we can do through custom way. We have done custom activity function during creation of event handlers to delete, update certain parameters, status change etc.
1. Go to IMG -> Event Management -> Event Handlers and Event Handler Data -> Event Handlers -> Define Activities for Updating Event Handlers
2. Create a new custom activity function in EH Update Activity Functions depends on your requirement.
3. Create Multitask EH Update activities and sequence first delete function and create on second step.
4. Assign Multitask EH Update activity in Event Type EH Upd.Acty 1 / EH Upd.Acty 2 on your Event Handler Type.
This can be achieved for same event handler.
Example: Refer this activity method PARAM_CHANGE_CUST - Add/Change/Delete Control and/or Info Param(s) Using Cust.
