Yeah, I tried that, but in the Employee -> New expenses voucher -> Edit
Expense Voucher list, right-clicking on the Description block doesn't
bring up any context menu (there isn't a memo block on this page).  Of
course, trying to do this in the target expense account doesn't work as
the transaction is automatically marked read-only.  

Maybe this is a bug?
