Why don't imported headers and footers display in Calc?

I am importing some ClarisWorks/AppleWorks spreadsheets into LibreOffice. Works perfectly except for one thing. There are headers and footers in the original spreadsheets and I can’t find a way to get them to display on my monitor in Calc.

The headers and footers do get imported (if I choose Import → Headers and Footers they do show up in the dialog box) and if I choose Print Preview they also show up. But if I want to work on the spreadsheet itself, the headers and footers are nowhere to be found.

Is there a way to get the headers and footers to show up on the monitor when I work on the spreadsheet in Calc (besides Print Preview)? I don’t want to print them; I just want to see the headers/footers on screen with the rest of the spreadsheet when I’m working on it. Thank you.
