How do I file form 1099-DIV for Nominee Distribution

I posted this on the "get your taxes done" board but hope for a second opinion on the Business board (perhaps from someone who has specific experience with this process). I am filing my mother's final return on form 1040.  I am also filing the 1041 under the calendar year for her trust.  This was a grantor trust under her SSN while she was alive.  As of the date of death it became irrevocable under a new EIN. She has dividend income received under her SSN from her brokerage. The dividends were from 5 separate mutual funds listed on a single document. Each fund had various boxes checked (1a, 1b, 2a, 3, and 5). Some of that income is pre-death and some post-death. It took a little work but I've figured out how to get all the values correctly entered into Turbo Tax (had to work around TT's method of proration).  Schedule B on the 1040 return has an adjustment for "Nominee Distribution" -- the sum total of all post-death ordinary dividends.  I understand I have to report this Nominee Distribution to the IRS and the trust by filing forms 1096 and 1099-DIV in order to "move" responsibility for this income from my mother's SSN to the trust's EIN.  The filing will list my mother as the "payer" and the trust as the "recipient". My question:

Can I file a single 1099-DIV to capture all the post-death dividends from the 5 separate mutual funds, OR do I have to file 5 separate 1099-DIVs (a 1099 for each mutual fund)?
