Train Travel in Alsace

A friend and I are walking from Strasbourg to Colmar in early May. We are flying into Paris and taking the train from there to Strasbourg.

We are thinking about leaving directly from Colmar. However, it’s clearly less expensive to book a round trip ticket from Paris to Strasbourg and return.

As the high-speed train from Colmar to Paris stops in Strasbourg on the way back to Paris, would we be able to book a round-trip ticket and then add a single ticket from Colmar to Strasbourg?

Is there a better way to do it? The train website is not too helpful, so any guidance you can offer would be most appreciated.
