Is there a way to fix it with Net-delay through EDA to meet Hold violations?

I am doing PnR and Timing ECO(ICC2, PT).
I want to do a hold fix.

However, the cell has a corner variation greater than the net delay. I know how to give net delay through manual work(insert buffer..), but I want to automate using EDA Tool.
 

Solution
"cell has a corner variation greater than net delay"
Can you elaborate?

If you have a hold violation, you could find all failing D pins, then add buffers that will fix those violations (without violating setup ofc) on those D pins. then do a quick legalize and eco route on those cells?

This could be done in a for loop. Another way i have used in the past, fix eco hold or a similar command in PT itself where you give it allowed buffers , list of failing endpoints, setup margin to maintain etc..
