Can we change "Save to USB" to use .jpg instead of .bmp?

POM

New DSO5102P with 191024 firmware update.

When I "save to USB", all the screen captures are greater than 1000KB and in .bmp format.  

In this Hantek forum (and others), the "Add Attachment" does not accept files greater than 1000KB and does not accept .bmp files.  

Is there a way to change the setting of the oscilloscope "Save to USB" function so that screen captures are saved as .jpg (which are often smaller than .bmp for the same image)?
