combine invest. accts

I have 2 401k investment accounts setup in quicken from previous employers. They have 2 mutual funds that are the same but named differently. How do I combine the 2 mutual funds shares into a single investment, in a new rollover account, and retain the cost information? I tried transferring one into the other account but quicken 2005 views them as 2 separate accounts. Any help would be apprecated. Thanks
