Delete the previous request from a DSO using Process Chain

[#1]

Hey everybody,

thats my current situation of the requests in my dso:

Basically, I just want to delete the previous request in my process chain and then activate the next one as normal.

I don't want to delete a request after a certain time or delete any overlapping requests.

Is there such an option in a process chain to delete the previous request, if so how?
