Quick thought to point out what @sappelhoff mentioned regarding subject specific stimuli here: https://github.com/bids-standard/bids-specification/pull/750#issuecomment-796591440 I don't think that it will such a rare case and we should probably give that...

Also does it make sense to have "prefix" or is it really shoehorning too much BIDS into this?

Can't think of something that would speak against using it from the top of my head. But it is currently an underslept and under caffeinated head so I may be...

By the way @melanieganz i am really tempted to take snippet of your top message to highlight the reasoning on how to use bids entities when naming files.

@agahkarakuzu do you see some reasons why we could not add a task entity to some of the qmri Anat files? I could not think of one but you know...
