Topic: Sentinel-2 MSI Ancillary Data

Dear Sir,
I am interested to perform sub-pixel correlation utilizing Sentinel-2 optical imagery. Does COSI-Corr allow to do that?
You know, while creating the ancillary file for Sentinel-2, the Sentinel-2 sensor is not shown and even this sensor is also missing in the opening external file option in ENVI.

Many thanks and appreciations in advance.
