Why not just use your Flexi for print and then just use Cut Studio to run the cutter?
Cut Studio is really really basic as far as design goes, but if you are able to use either Ai/DRAW/Inkscape/Flexi to design, you can use Cut Studio to cut from. There are plugins for Ai/DRAW for Cut Studio to help with placements of reg point etc if you don't want to manually deal with that.
