Live feature request - upload mask or volume from web browser


Often when using Live, I would like to upload a mask or volume, for example to run local refinement on the particles generated from Live. Currently this is is a bit awkward, particularly on a facility GPU where one might only have easy access to the web interface. Would it be possible to add the capability to upload a file directly from a local directory via the web interface? This would be particularly useful in Live, but would also be useful in regular cryoSPARC.
