How to snap app access to /data in sandbox? Is it possible?

I searched this forum and found some similar topics.

I think these options are available.

  1. mount -obind /data /home/data
  2. use removable-media interface
  3. classic confinement

But, if I must use direct /data not mounted directory(/home/data or /mnt/data), Is there any possible way?

thanks.
