How to skip owners in the workflow

How to skip owners in workflow
For example, Company A is at hierarchy 3 (terminal organization) and wants to pass approval to Company C at hierarchy 2 (middle hierarchy) and then to hierarchy 1 (upper hierarchy).
Hierarchy 3 (terminal organization) → hierarchy 2 (middle hierarchy) → hierarchy 1 (upper hierarchy)
On the other hand, Company B at hierarchy 3 (terminal organization) wants to send the approval to hierarchy 1 (upper hierarchy). In other words, it wants to skip Company C at hierarchy 2 (middle hierarchy).
Hierarchy 3 (Terminal organization) → Hierarchy 1 (Upper hierarchy)
Companies A and B are subordinate organizations of Company C.
I want to skip the owner in the workflow, so please let me know.
