Spectra S1/Bottle compatibility question

Ca

I’m a FTM and I’ve been doing some research and am thinking of getting the Spectra S1. It looks like it is not compatible with very many types of bottles though. Is this a problem, or do you just pump into whatever bottle fits the machine and then pour the breastmilk into the bottle your baby prefers? I’m planning to exclusively breastfeed at first and then transition to some bottle feeding for nighttime and for once I have to go back to work. Thanks for any insight, I have NO idea what I am doing!
