I've searched around and come up with nothing, so perhaps it is not possible, but I thought it was worth asking

I was wondering whether it was possible to access / use / implement a 'private' clipboard for Excel.
At the moment it uses the Windows general clipboard as would be expected.
However I have a long running macro that is consolodating data by performing multiple copy/paste operations between worksheets and workbooks.
As it stands, I cannot copy & paste in any other windows application whilst my consolodating macro is running, because anything I place onto the clipboard is almost instantly overwritten with the data that Excel is copying & pasting.

Is there anyway to get Excel to use a private clipboard, that would remain local to the Excel process and not affect the main Windows clipboard?

Thanks
