Chain multiple comands in a qapp/parser in one cli session

Hello all,

I would like to write an parser/qapp for a fortinet to capture some packets.

Here a chain of commands is used to archieve a packet sniff.

diagnose debug flow filter port 443                             ##Define Filter
diagnose debug flow show function-name enable
diagnose debug flow show iprope enable
diagnose debug flow trace start 20
diagnose debug enable

diagnose debug disable
diagnose debug flow filter clear                                  ## Output start, need to be captured

##cleanup

diagnose debug disable
diagnose debug flow filter clear

The flow must be in the same CLI session (I already tried to use a standalone parser for each step)

On the fortinet box itself it is not possible to chain commands.

Is that possible?
