Dear Conn user

I was wondering whether there is a module function to enable simultaneous filtering (before nuisance regression, filtering of nuisance included).
My syntax looks as follows:

conn_module( 'preprocessing', ...
'structurals', {'/Volumes/My_Book/test/anat.nii'}, ...
'functionals', {'/Volumes/My_Book/test/f.nii'}, ...
'steps', {'default_mni', 'functional_regression', 'functional_bandpass'}, ...
'sliceorder', 'ascending', ...
'fwhm', 6, ...
'reg_names', {'realignment','scrubbing','White Matter','CSF'}, ...
'reg_dimensions',[inf, inf, 5, 5], ...
'reg_deriv', [1, 0, 0, 0], ...
'bp_filter', [0.008 0.09])

Can I just inverse the order of 'functional_regression' and 'functional_bandpass'?
Or should I add another term so that the nuisance regressors are filtered too? 
Will the scrubbing regressors also be filtered and is this likely to add a confound?

Thanks
