100% agree with this, the inability to add custom fields to job assignments (and organisations) feels like a real gap functionality-wise. Once we've transitioned to Totara Perform (when appraisals can finally be properly assigned per-job), we will be looking at multiple job assignments as our next project. Not being able to record additional items of information (not just FTE, but job coding, staff group, etc.) is likely to be a blocker for us doing that.
