Subsurface doesn't track cylinders but rather the gases you use so unless
your dive computer has a switch event indicating that you have used more
that one gas mix only one gas mix and by definition only one cylinder will
be shown in the UI.
Due to the limited screen size of the average mobile device some options
are not implemented, the option of adding extra cylinders is one of them.
You have a couple of options to choose from:
1# Use a cylinder specification that is the twinset version of the
cylinders you use. This is the simplest way to get more accurately tracked
gas consumption values.
2# Define a second gas in your dive computer and roughly halfway through
your dive you perform a gas switch to the second gas. Depending on if your
DC/libdivcomputer sends a gas ID together with the mix you might have to
set up the gases with different fO2 i.e. 21&22 & O2 or add 1% He to the
second gas mix in order to make them different. This will get you two gases
and thus two cylinders automatically in both the desktop and mobile version.
3# Use tank pods to get real time data of you gas usages.
