Automatically assign values for one column based on another column with options from second list

[John603]

Okay I will try to explain this as best as I can. I hope I am not re-asking a question but I couldn't find anything that matched my problem:

I have two SharePoint Lists:

List 1 = Requests - Collects data from users using a form and this list is the primary list that the end user does not see.

List 2 = Option Coordinators - Defines roles to my team members (set up so this coordinator can be changes as people move in/out of the department).

What I am trying to do:

1. The user selects which "option" they want in List 1

2. What I want is the "option" in List 1 to assign an "option coordinator" from List 2 automatically (Power Automate).

Note in List 2 has columns of "Option" and "Option Coordinator". 

Any help would be appreciated

@John603 What is the column/data type of Option and Option Coordinator column in the List 2?

If it is a single line of text, you can do this:

1. Create a lookup column in list 1 which will point to list 2
2. Use main column as option 
3. Extend lookup and use additional column for Option Coordinator in lookup settings: 

Check these documentations for more information:

1. Create list relationships by using lookup columns 
2. Create a column in a list or library
