Since I looked for hours and couldn't find an exact answer to what I needed I thought I would post the answer I come up with.
+To add attachments to an individual feature within a feature class in a sde database:
Note: These instructions assume that attachments are already configured for the layer in question.
1. Start editing the workspace or layer that wish to add attachments to.
2. Select the feature you would like to add the attachment to, right-click on it and select â??Attributesâ?�
3. The Attributes window will appear.
4. Using the attachment manager, choose â??Addâ?� to add a new attachment. Can be any format, but the primary ones you will be adding are PDF and JPEG.
5. Close the dialog and you will now see you attachment listed under the Attachments drop down. If you are not in an editing session your attachments will be available when you use the identify tool.
6. Save your edits and stop editing.
