You don't have to save ALL the seeds from a given tomato. Save 2-3 if that's what you have space for.
>>that requires me to remember which of all the plants I harvested the previous saved seed from!<<
Options include:
* Save seeds from the first tomato to ripen seeds, mark that plant with a string or a label stuck next to it, then mark the other plants as they set seeds.
* Save one tomato from each plant at the same time.
