Freemarker datamodel pollution

I have started to user Freemarker to generate some output based on a datamodel. The issue I face is that I keep exposing methods in my datamodel for the sake of my output generation. So I have the feeling to "pollute" my datamodel for the sole sake of my Freemarker template.

Here is an example:
My datamodel, which is an interface in my case, provides this method (changed names and types for illustration):

Collection<MyPojo> getMyPojos();

In order to write the template the way I imagine it, I need to filter some of MyPojo based on some condition. I wanted first to do it in the template itself but it appeared quite complicated to manipulate lists within the template.
So I ended up adding other methods in my interface to cover the needs:

Collection<MyPojo> getAddedMyPojos();
Collection<MyPojo> getRemovedMyPojos();

Reading the Freemarker documentation, I didn't found a way to use some Fremarker API to provide more method to the template processor.
Is there any smarter way with Freemarker to achieve this goal? I would like to keep my interface clean with only the first method. Do I need to create a dedicated datamodel, extending my initial datamodel? Or to create a Map and to inject this one instead of my datamodel (and to populate it with the results of my methods)?

Thanks!

As proposed by Glenn Lane it's better to isolate the code for Freemarker. So implementing a dedicated POJO
