updating table from different document using workflow

I have a HR file cabinet where students are created via a form. When created, a table is filled with a list of tasks. 
Every new document regarding this student the table from the first document should be updated with the task being done. Is this possible?

Form (first document) 
Task 1:
Task 2: 
Task 3:

---

New document regarding Task 1 (second document)

----

Update (first document)
Task 1: Done! Second document uploaded
Task 2: 
Task 3:
