How to specify what segmentation is associated with an image?

From version: eef16bcb5e84cf73b570a2b98c99288b4f7fd23f

After loading a folder (checked no BIDS), I'm seeing the list of NIfTi images:

But at this point, what is unclear to me is:

how can I associate the existing segmentation (that are located under the derivatives folder) with each image?
for new segmentation, how can I specify their file name upon saving?

There is a path that is shown below the 'interpolate' button:

What does this path correspond to? If it is the segmentation, I suggest adding a clear title above that path to indicate what this is. Also, if it is the segmentation, then what is the logic to retrieve that file name? I see it is under derivatives, but nowhere in the config I specified that path:

Also, more problematic: that file name refers to the wrong segmentation (the subject name does not match between the image and the seg).
