title: adding a sequence to an existing table
body: <p>i created a table but i forgot to add a sequence to one of the PK, its a sequence on a form page, i just cant find anything about it, is it possible or do i have to do the form all over again.
  i tried to replace the PK but it doesnt give me the option to add the sequence when creating a new one.
  i searched everywhere and asked the support in chat (didn't really help since its not their job).
  all i could find was <a href="https://docs.oracle.com/en/database/oracle/application-express/18.2/aeutl/managing-sequences.html#GUID-E177ACD2-7FCD-4536-974B-62D7E84576C3" rel="nofollow noreferrer">this</a> and <a href="https://docs.oracle.com/en/database/oracle/application-express/18.2/aeutl/managing-tables.html#GUID-B21034CD-D55E-47DF-9042-237C5F98A369" rel="nofollow noreferrer">this</a>.</p>
