If I’d like to attach someone’s training certificate, your current workflow makes this a two step process.
1. Enter in training date, and details. (note the lack of ‘Certificate’ area and inability to attach files). Save.
2. Edit the training you just entered. Add attachment. Save.
Please consider making the two UI functionally the same, so this work can be done in one step.
The “Add attachment” button should be available when first entering in training. See attachment for example/detail.
