Alternantives to an independant 4 jaw chuck for a cnc lathe

I replaced my SL-10 and TL-1 lathes last year with an Okuma Genos L300M lathe. The only capability I lost is the independent 4 jaw chuck on the TL-1. Is there an alternative for a cnc lathe with a hydraulic drawtube? Hopefully something the drawtube could actuate. Or should I just look for a 4 jaw that fits my spindle and forget about the draw tube.

Thanks in advance :cheers:
