Is it possible to write a flow to update a Sharepoint List Item Field by searching for that Items' ID number in another List, and returning all the ID numbers of the multiple records in the new list that have the ID number from the first list, and have those new ID numbers added to the first list as links back to their associated item? I've done this for a one-to-one lookup, but not one-to-multiple and wasn't sure how to get started.
This is how I would want it to look after the update. Both IDs are unique to their respective table.
List 1 ID List 1 Name List 2 IDs
ID-01 Name 1 ID-01-01,
ID-01-02
List 2 ID List 1 ID List 2 Name
ID-01-01 ID-01 Name 1.1
ID-01-02 ID-01 Name 1.2
Thanks!
