Rev Table with Workgoup PDM - Approval box???

Could anyone give me a bit of advice,

I have just set up workgroup pdm at a company I have started at. I have got it partially working, and am currently testing to ensure its robustness.

I have created drawing templates which use Revision table function that is populated from PDM data. This is working great so far, however I have added a column to the table to include Approval initials.

Does anyone have any experience of this? This field is not automatically filled in on checking into the PDM. and so I thought that perhaps I would need to implement lifecycle process, and have a stage for checking.

I found that this simply wants to bump the revision, and obviously add another row to the rev table.

Attached is our sample drawing template.
