Dear Tarik,
a monthly view could be added, but we should be clear about the requirement.
The transition monitoring currently has a daily view, because the daily view is more "responsive" than a monthly aggregation. It shows changes almost immediately, allowing to know when a change happened.
For a monthly aggregation we would have to define how stations should be displayed, for example if they were in GTS only for some days and then in WIS2 and GTS for some other days. The result could be confusing to some users.
What would be you use-case for for a monthly aggregation?
with kind regards,
Timo
