Allow duplicate values in user profile field (String MV)

Hi,

In our Sharepoint 2010 Server enviroment i am trying to achieve the following.
Users fill in their location from a Term set with pre-defined options. Depending on which locations are selected i am running an import from a SQL database which gives me the names of the city's the locations are in.

Lets say user User01 has the following locations in the location field:
Main Office; Finance; IT;

The city's these offices are in:
Amsterdam; Amsterdam; Berlin;

The SQL import will run on user profile sync and show me the following values:
Amsterdam; Berlin;

The second Amsterdam will not be filled because it is a duplicate, but in my XSL for search it is important to maintain the sequence. Is it possible to keep the duplicate values in a String (Multi-value) user profile property?

Thanks in advance,
Strakkie
