Is there a way to add some sort of progress bar to a worksheet, whilst the sheet is re-calculating?

I have just added the option to filter a large data set, (around 1 million cells) using 'radio buttons', with a lot of help from Ace_XL. The 'problem' is that it takes around six or seven seconds for the data to 'recalculate' and for the selected radio button to show as checked and so to the user, it looks as though nothing is happening. I realise there is a progress bar in the status bar, however, a) when clicking on a cell at the top of the worksheet, the user doesn't tend to look down there and b) the status bar is going to be hidden on the worksheet, so they wouldn't see it anyway.

To prevent this I would like to somehow replicate the progress bar on the worksheet itself, so the user can see that something is happening when they click the relevant radio button. Is this possible to do and if so, can anyone provide a sample or some ideas as to how this could work?

Many thanks
