You can do this: create a tex tbox on the spec sheet and with the text tool still selected, go to the hyperlink panel, select “new hyperlink destination”, the next panel asks you for a name for the “text anchor”. Put in a distinct name.
Next go to the page you want to link from and create a button. In the button panel select as action “go to destination” and link it to the previously created anchor.
