omega DIPA yeast question

So I brewed todaya 5gal batch and will pitch tomorrow. (I do no chill) and i did a 2 cup 1035 gravity starter with the above yeast. I did the starter yesterday morning and its ripping already. My question is can I split this starter and keep half for my next brew? My final gravity for the beer im pitching this into is 1057…

Two cups is pretty small and you aren’t getting much growth. Pitch the whole lot and save some after this beer is done.
