FIM Portal Email Templates

I have a requirement to use a multi-valued attribute in the body of an email template. Currently if I just inject the values from the attribute using the default method I get a jumbled mess of data.

What I would like to do is format the data from the mult-valued attribute to make it more readable by adding a CR/LF between each value in the list e.g.

Table Heading1:    Mult-valued attribute, text string1

                           Mult-valued attribute, text string2

                           Mult-valued attribute, text string3

                           ...

So far I cannot see how this can be achieved as any substitutions I make to try and add CR/LF or even make any change to the data seems to be ignored.

Is there any way to achieve this?

Thanks
