Multiple users accounts to the same Robot

Hello! the summary of my question is whether is it possible for the same Robot to utilize multiple user accounts instead of one, below is an explanation:
Executing the following process as the following scenario 1:
Process: A
Username: userName_1
License: unattended (A)
VM: A
Robot: Prod 1
however due to contradicting access policies, this Robot will need to execute the another process on another username as following:
Process: B
Username: UserName_2
License: unattended (A)
VM: A
Robot: Prod 1
is this possible? and what I mean by possible not us having manually to update the username and password on orchestrator but done automatically.
