(tableTools) Can we Use Flash Option Buttons within a Button Collection ?

This ist about the Extension tableTools.
Is is possible to use "Flash button options" (ie. sFileName, oSelectorOpts, ...) within a Button Collection.

how can we to this, this would be very useful.

ie.

tableTools: {
              aButtons: [
              {
                sExtends:         'collection',
                sButtonText:      'Export to',
                aButtons:         [  'csv', 'xls', 'pdf' ]

                can we define these options for csv, xls, pdf separately
                sFileName:        'FileName.pdf',
                sFileName:        'FileName.xls',
                or
                oSelectorOpts: { page: 'current' }
              },

PS: Dear Allan, this is an fantastic piece of software. I love it!
