In excel we can have a cell which content automatically changes based on what is in another cell.
Example
Cell 1 Cell 2
+----------+------------+
| tuesday | 01/02/1980 |
+----------+------------+
| thursday | 03/02/1980 |
+----------+------------+
Cell 1 automatically changes based on the date in Cell 2.
Can we achieve similar in Photoshop? I have some text fields which must be the same in other areas of the document, rather than duplicate layers and manually move them around, I would rather just edit one field and the rest change automatically.
