yes, there is.
there are 2 crucial facts to know, after that you can get creative.
a) A "total column" can span multiple browse columns. thus, say your amount column is column 4, then you can have a total (in column 1) which spans 3 columns, and thus gives you space to put whatever you want.
b) The _contents_ of the total column can vary. From the drop-down are the obvious, Sum, Average and Count, but there's also "Custom". And that does exactly what it implies. So if your total for column 1, spanned 3 columns, and was set to custom and the custom total was set to
'Total of all Current Invoices:'
then you're on your way.
Obviously you can repeat for column 5 to put stuff after the total. (Hopefully there is a column 5...)
