How do I make the DDR Simfiles compatible for StepF2?

I've being playing some DDR and PIU for quite some time now and I just wanted to ask how do I add the simfiles from Stepmania to StepF2? Is there a way to do so?

From what i know, SSC files created under the "Pump" game mode in Stepmania (the mode can be changed via settings, in the "Select Game" option) are normally compatible with StepF2.
When it comes to adding the "Dance" mode (the "default" game mode in Stepmania) in StepF2, however, i don't think there's a way.
