Does the amount of grad school matters to recommenders?

I am applying to grad programs in 2 fields, closely related, but that means not 6 applications but rather 12. Will recommenders care? I assume they will write one letter and just submit it 12 times, right?

It really depends on the professor. Some professors will personalize it slightly to the universities and programs.  They might also choose to emphasize certain parts of you to different programs depending on their strengths.
