Is it possible to run a function on a Silverstripe template variable to format output?

Question

I've created a data model that includes a plain textarea entry field for an office address. I would like to do the equivalent of nl2br($OfficeAddr) when printing the data in my relevant Silverstripe template. As far as I can tell, their templating system does not support such functionality.

Am I missing something? Any recommended workarounds?
